[Bug 1987159] Re: Drop VNC support from GNOME Remote Desktop in Kinetic

2023-07-10 Thread Alkis Georgopoulos
> I am struggling to find any use cases where GNOME's VNC should be
preferred to RDP.

1) Teacher screen broadcasting to students. There, a shared VNC session
is much easier to setup and performs better than separate RDP sessions.
Additionally, encrypting e.g. 10 RDP streams comes with significant CPU
strain, which is unnecessary in this use case.

2) The remote support use case. To help a remote user behind NAT, I only need 
to ask them to run `x11vnc -connect my-ip`. On my side, `vncviewer -listen` 
accepts the request for help.
GNOME VNC could easily support that. But there's no `xfreerdp -listen` option 
in the RDP protocol.
So in the RDP solution, the very frequent and significant "remote support" use 
case is completely ignored and we need to switch to teamviewer or anydesk 
instead.


It's understandable though that if upstream GNOME neglects VNC, downstream 
Ubuntu will also do the same. And such decisions are why there's a growing list 
of users that can't use GNOME at all anymore...

[Bug 1762952] Re: Alternative shortcut for layout switching Alt+Shift unexpectedly set by default

2020-08-18 Thread Alkis Georgopoulos
Hi, this fix caused a regression in ubiquity: LP: #1892014

Ubiquity doesn't put alt_shift_toggle in XKBOPTIONS anymore, so we
cannot switch to e.g. Greek using Alt+Shift, after going through a
normal installation (or even in the live session).

Are users expected to manually run `dpkg-reconfigure keyboard-
configuration` right after a GUI installation of Ubuntu?

E.g. ubuntu-mate-18.04.2-desktop-amd64.iso is affected while 18.04.1
isn't.

Should this issue be resolved in console-setup or in ubiquity?

[Bug 1861481] Re: language-options causes live CD sessions to be untranslated

2020-02-05 Thread Alkis Georgopoulos
The reason that this regression doesn't affect ubuntu-desktop, might be
that unlike LightDM, GDM doesn't have that Ubuntu-specific patch to use
/usr/share/language-tools/language-options.

So, I subscribed "lightdm (Ubuntu)" to the affected packages, in case we
just want to drop the Ubuntu-specific patch, and that way make lightdm
not pass LANGUAGE when it shouldn't.

I think that this won't address the source of the regression, but it
will make the problem not appear in flavors that use lightdm which
should be good enough.

[Bug 1861481] [NEW] language-options causes live CD sessions to be untranslated

2020-01-31 Thread Alkis Georgopoulos
Public bug reported:

Since Ubuntu 19.10, for all Ubuntu live CDs that use LightDM (e.g. MATE
and Xubuntu), if a user selects a language in syslinux other than those
with an included langpack, the session is then untranslated.

For example, if one boots Ubuntu MATE 20.04 and selects Greek in
syslinux, he ends up with LANGUAGE=en in the session.

The chain of events is:
LightDM has an Ubuntu-specific patch that makes it call 
/usr/share/language-tools/language-options instead of the upstream `locale -a`.
`locale -a` does list el_GR as a supported locale because casper correctly 
updated the locales.
But language-options doesn't list el_GR, so it fools LightDM into thinking that 
Greek aren't supported; while they're all there, since e.g. MATE doesn't rely 
on langpacks; mate-panel.mo and mate-calc.mo etc are all there.

I believe the correct fix would be for language-options to list el_GR on
live CDs (to merge the output of locale -a in its output).

Thanks!

[Bug 388547]

2018-12-17 Thread Alkis Georgopoulos
This issue got *much* worse recently, it now affects keyboard layout
switching as well, so many applications like tuxpaint became completely
unusable.

Example: In Ubuntu 14.04, I run `tuxpaint --fullscreen`. I press Win+Space, the 
Gnome-defined method to switch my keyboard layout from "us,gr" to "gr,us".
unity-settings-daemon cannot read the layout change because tuxpaint has the 
keyboard grab.
(It's the same in other distros too, it's not Ubuntu specific)

So I can't type Greek with the tuxpaint Text tool, making tuxpaint
completely useless in fullscreen mode.

Until some years ago, Gnome allowed XKB to manage the layout switching, which 
worked fine even in fullscreen applications.
It no longer allows it, they try to manage it with gnome-settings-daemon etc.

If there's no intention to fix this in Xorg, please mention it here, so
that we can show that response to Gnome developers and tell them to let
XKB manage the keyboard layouts instead.

[Bug 1767765] [NEW] Clicking on fcitx applet hangs Ubuntu MATE

2018-04-29 Thread Alkis Georgopoulos
Public bug reported:

Method to reproduce in 1 minute:
1) Download the Ubuntu MATE 18.04 live CD.
2) Press space while booting to display the syslinux language menu. Select 
Ελληνικά (Greek) in order for fcitx to autorun. I guess the same will happen in 
other languages too.
3) Select Δοκιμάστε το Ubuntu MATE χωρίς εγκατάσταση (Try Ubuntu MATE without 
installing).
4) When the live session becomes available, the following applets show:
en [keyboard icon] ...
At that point, clicking on the keyboard icon causes no issues.
5) Open anything that displays a cursor, e.g. a terminal. Now the following 
applets show:
en [keyboard icon] us
It is a bug that the language is shown twice. But the main problem now is that 
if one clicks at the keyboard icon, an unpopulated (hanged) menu shows up, and 
the keyboard/mouse no longer work; no interaction with the desktop is possible.
6) If one presses Alt+Ctrl+F2 to switch to vt2, logs in with ubuntu-mate and 
empty pass, and types `killall fcitx`, and then presses Alt+Ctrl+F7 to switch 
back to vt7, the UI is unfrozen and works properly.

[Bug 1739732] [NEW] Can't switch to Greek in Ubiquity when fcitx is running

2017-12-22 Thread Alkis Georgopoulos
Public bug reported:

I boot with the current Ubuntu MATE 18.04 daily live CD. I select Greek
on syslinux, "Try Ubuntu before installing", and I start the Ubiquity
installer.

At the step where I'm supposed to type my full name, for example "Διαχειριστής" 
(administrator), I can't switch my keyboard layout to Greek. Neither Alt+Shift 
nor the panel applet allow me to switch.
Note that there are 2 panel applets, MATE's and fcitx's, and both have entries 
for Greek and English, but when I click on Greek, nothing happens.

If I switch to any other application, like e.g. mate-terminal, I can
properly switch to Greek. But, if I go back to Ubiquity, I automatically
get switched back to English.

If I exit fcitx from the panel, then everything works fine in Ubiquity as well.
If I rerun fcitx, the problem starts again, so it's completely reproducible.

Btw, is fcitx supposed to be running in the Greek locale? Or is this an 
additional issue with im-config?
And is it normal to have 2 applets for keyboard layout selection?!

[Bug 1605571] [NEW] apt install --no-install-recommends fcitx-bin, breaks dead keys

2016-07-22 Thread Alkis Georgopoulos
Public bug reported:

Test case: remove everything related to fcitx.
Then run: apt install --no-install-recommends fcitx-bin
Then login with some locale that uses dead keys, for example the Greek locale.
Then type e.g. ";"+"a". It's supposed to show "ά", but instead it shows "´α".

At that point, fcitx isn't running, yet `im-config -a` reports that it's the 
selected input method.
$ env | egrep '_IM|XMOD'
CLUTTER_IM_MODULE=xim
QT_IM_MODULE=xim
XMODIFIERS=@im=fcitx
QT4_IM_MODULE=xim
GTK_IM_MODULE=xim

If fcitx-bin is installed along with all its recommended dependencies, then 
fcitx is running normally and the issue described above doesn't occur anymore. 
At that point, the environment variables are:
$ env | egrep '_IM|XMOD'
CLUTTER_IM_MODULE=xim
QT_IM_MODULE=fcitx
XMODIFIERS=@im=fcitx
QT4_IM_MODULE=fcitx
GTK_IM_MODULE=fcitx

At present I've only tested with the MATE desktop environment.
It also happens with the MATE live CD, as fcitx-bin is indeed preinstalled 
there without its recommended dependencies.

I'm having a hard time applying all the last e.g. 20 upstream commits to
the Xenial tree.

@Dmitry, since you'll be merging the upstream with the Ubuntu tree anyway in 
order to test it youself,
would it be possible to push the result somewhere, e.g. in launchpad,
or publish a .deb in a PPA,
so that it's easier for me to test it?


In general, it'd be nice to have a launchpad recipe that builds upstream 
gnome-flashback + ubuntu packaging to some PPA, so that we can test things more 
easily.

E.g. this is what I have for testing LTSP upstream:

Hi Alberts,

I tried applying the latest 13 commits from the test-3-18 branch on top
of Xenial's metacity.

If my benchmarks were correct, it made things even slower.

glmark2 score:
xenial-metacity --no-composite: 311
test-3-18-metacity --no-composite: 154
xenial-marco --no-composite: 902

I.e. now it's 6 times, rather than 3 times, slower than marco...

Can we use marco instead? Doesn't it additionally have CSD support?

Or, could end users of gnome-flashback-session decide to install and use
marco instead of metacity without bumping into major issues?

[Bug 1566157] Re: Metacity's compositing is too slow

2016-04-08 Thread Alkis Georgopoulos
To sum up, two problems:

1) `metacity (and marco) --composite` in 12.04 and 14.04 had only 60% of the 
compiz performance.
2) `metacity` (both composite and no-composite) got a lot slower in 16.04, at 
60% and 25% respectively of the compiz performance.

[Bug 1566157] Re: Metacity's compositing is too slow

2016-04-08 Thread Alkis Georgopoulos
> Any chance that you could track down version when it started to be slow?
> Was composite already slow in previous LTS?

Initial tests show that metacity had about the same performance as marco in 
12.04 and in 14.04.
In those versions, `metacity (or marco) --composite` performs only about 60% as 
well as `metacity --no-composite`,
while `compiz` performs about the same as `metacity --no-composite`.
glxgears example:
no-wm: 394.117 
compiz: 393.603
metacity --no-composite: 403.858
metacity --composite: 239.124
marco --no-composite: 404.455
marco --composite: 242.672

Unfortunately in 16.04 it got a whole lot worse, for example:
no-wm: 469.506
compiz: 467.071
metacity --no-composite: 277.188
metacity --composite: 122.936
marco --no-composite: 464.281
marco --composite: 287.314
xcompmgr: 291.990

Now `marco --composite` is still at 60%, while `metacity --composite` is now at 
only 25% of the optimal performance.
But note that `metacity --no-composite` is also a whole lot worse than `marco 
--no-composite`.

Alberts do you want me to try with non-LTS releases as well?

These tests were made by running a plain `xinit` (which gives a simple
xterm) on top of a usual Ubuntu gnome-flashback installation, while also
installing marco there.

[Bug 1512002] Re: Annoying dialog "Authentication is required to change your own user data"

2016-04-08 Thread Alkis Georgopoulos
mterry, charlesk, I took the liberty of subscribing you because I think it 
involves this commit:
https://code.launchpad.net/~mterry/indicator-messages/tell-accounts-services/+merge/93290

The issue is happening to me as well, on Ubuntu 16.04 gnome-flashback, in 2 
cases:
1) sometimes when I try to unlock the screensaver,
2) sometimes when I login via ltsp thin/fat clients.

I think the problem is the one mentioned by khadgaray in
https://bugs.launchpad.net/ubuntu/+source/indicator-
messages/+bug/1192300.

I.e. that the system is trying to notify us if we have new mails etc,
and that for some reason(s) it's considering us an "inactive user"
(inactive means not in the active screen of the pc, either remote or in
a screensaver etc) and thus we need authentication.

The necessary rights are defined in this file:
/usr/share/polkit-1/actions/org.freedesktop.accounts.policy

  
...

  auth_self
  auth_self
  yes

...

I think that if we change "auth_self"
to "yes",
we'll have a temporary workaround to the problem.

But the real issue is, should the system consider us "inactive" in the screen 
saver?
Should it consider us inactive in ltsp thin clients that are remote sessions?
Should it consider us inactive in ltsp fat clients where accountsservice 
doesn't have information about the remote user account? (similar with ldap)

If the answer to the above is yes, then maybe the workaround that I
mentioned above should be committed to accountsservice?

Yet another benchmark, glmark2, in a very recent core i5 client.

Scores:
No WM: 2058
marco --no-composite: 1894
compiz : 1878
metacity --no-composite: 742
xcompmgr: 716
marco --composite: 708
metacity --composite: 441

In an ideal world, gnome-flashback would support compiz first, then
`metacity --no-composite` but with the speed of `marco --no-composite`.

They're 4-5 times faster than the proposed `metacity --composite`!!!

/me will definitely ask the Mate people if they still support `marco
--no-composite`...

[Bug 1565640] Re: Set compositing-manager=false by default

2016-04-06 Thread Alkis Georgopoulos
> Probably way easier is to document, to execute in terminal:
> gsettings set org.gnome.metacity compositing-manager false

It's easy for one sysadmin to run a few commands in a terminal.
It's not easy for hundreds of students, e.g. 5-10 years old, to run a few 
commands in a terminal.

Sysadmins (or packagers) can provide a system-wide override with 
/usr/share/glib-2.0/schemas/20_metacity.override
but that will only work with new users.
They can provide overrides for all users with mandatory gsettings.

But the /usr/local/bin/metacity wrapper can have logic to active or
deactivate compositing per user, or per machine, based on the CPU, the
graphics card etc etc, and it's very easy to integrate it with LTSP.

Anyway that part isn't important; the most important thing is if the 
non-compositing case will be a supported use case in Ubuntu gnome-flashback 
16.04 or not.
I'll do some more benchmarks with gnome-flashback and with other DEs like 
Mate/XFCE/LXDE.

Thank you guys!

2016-04-05 Thread Alkis Georgopoulos
> @Alberts, I'll do some more tests and come up with hard numbers
concerning the performance of metacity with or without compositing.

I did some benchmarks and reported them in
https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1566157

Now I'm more convinced that metacity's compositing-manager should be
false by default. For LTSP users, I'll document how to create a
/usr/local/bin/metacity wrapper that launches `metacity --no-composite`.

Quoting my conclusions from that bug report:

I really think that the user's choices would be:
1) compiz, for every PC that supports it,
2) metacity --no-composite, for any PC that doesn't support compiz and that 
isn't able to spare 50%-80% of their FPS,
3) metacity --composite, ONLY for the minority of the PCs with graphics cards 
that can't run compiz and with so awesome CPUs that can spare 50-80% of their 
FPS. If you can find an example of such a PC, please let me know, currently I 
don't know of any. I do know of thousands of examples in category (2) though.

Since `metacity --composite` is so much slower, affecting all apps and actions 
from simple drawing to scrolling to moving around windows to watching videos to 
game playing etc,
I'd like to again ask you to consider NOT making (3) the preferred session for 
gnome-flashback for 16.04.

I.e. gnome-flashback-compiz could be the default (proposed one),
and gnome-flashback-metacity the non composited version,
with the --composite option only available as a gsetting for the minority of 
the people that would need it.

Thanks!

And here are some numbers for glxgears again (on another pc), but with xcompmgr

The first column is the WM used, the second is the FPS for glxgears, and the 
third the FPS for glxgears -fullscreen:

metacity --no-composite 170 15
metacity --composite83  7
compiz  225 15
xcompmgr122 7
compton 102 7

`metacity --composite` is again about 3 times slower than no-wm and compiz.
With appropriate fixes, it should be able to reach at least the performance of 
xcompmgr, shouldn't it?

2016-04-05 Thread Alkis Georgopoulos
I run another set of benchmarks using x11perf.
I don't know how much they can help in pinpointing the issue(s), but they do 
show that `metacity --composite` is extremely slower than `metacity 
--no-composite` or `compiz`.

I'm attaching the output in LibreOffice Calc format, I think it's more
readable that way.

An example line from the attached .ods file:
Test: 500x500 tiled rectangle (17x15 tile)
no WM: 772 (100 %)
metacity --no-composite: 699 (91%)
metacity --composite: 233 (30 %)
compiz: 688 (89 %)

The numbers are the repetitions, and inside the parentheses are the normalized 
values, with 100% being the highest.
The others are about 90% efficient, while `metacity --composite` is only 30% 
efficient, three times slower in that test.

I can also create a similar .ods for gtkperf, if anyone thinks that it
will somehow help.

[Bug 1566157] [NEW] Metacity's compositing is too slow

2016-04-04 Thread Alkis Georgopoulos
Public bug reported:

I did the following benchmarks between `metacity --no-composite`,
`metacity --composite`, and `compiz`, in Ubuntu 16.04.

First, I disabled vsync:
$ cat ~/.drirc 






Then I ran glxgears as follows:

$ metacity --no-composite --replace & sleep 5 && glxgears & sleep 20 && killall 
glxgears
29564 frames in 5.0 seconds = 5912.721 FPS
29729 frames in 5.0 seconds = 5945.777 FPS

$ metacity --composite --replace & sleep 5 && glxgears & sleep 20 && killall 
glxgears
10366 frames in 5.0 seconds = 2073.057 FPS
10194 frames in 5.0 seconds = 2038.702 FPS

$ compiz --replace & sleep 5 && glxgears & sleep 20 && killall glxgears
37633 frames in 5.0 seconds = 7522.813 FPS
37990 frames in 5.0 seconds = 7597.965 FPS

As a second set of benchmarks, I ran glxgears -fullscreen as follows:

$ metacity --no-composite --replace & sleep 5 && glxgears -fullscreen & sleep 
20 && killall glxgears
1652 frames in 5.0 seconds = 330.296 FPS
1667 frames in 5.0 seconds = 333.281 FPS

$ metacity --composite --replace & sleep 5 && glxgears -fullscreen & sleep 20 
&& killall glxgears
886 frames in 5.0 seconds = 177.007 FPS
891 frames in 5.0 seconds = 178.099 FPS

$ compiz --replace & sleep 5 && glxgears -fullscreen & sleep 20 && killall 
glxgears
1830 frames in 5.0 seconds = 365.868 FPS
1847 frames in 5.0 seconds = 369.242 FPS


Normalized results (with compiz=100):

Windowed:
metacity --no-composite: 78 FPS
metacity --composite: 27 FPS
compiz: 100 FPS

Full screen:
metacity --no-composite: 90 FPS
metacity --composite: 48 FPS
compiz: 100 FPS

So `metacity --composite` in this test was about 2 times slower than
`metacity --no-composite` and about 3 times slower than `compiz`.

This test was done an "Intel(R) Core(TM) i5-4440 CPU @ 3.10GHz" CPU, with the 
following embedded graphics card:
$ lspci -nn -k | grep -A 2 VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200 v3/4th 
Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)
Subsystem: Gigabyte Technology Co., Ltd Xeon E3-1200 v3/4th Gen Core 
Processor Integrated Graphics Controller [1458:d000]
Kernel driver in use: i915

I'll upload more tests if I find anything newsworthy.

That's a good example, does that mean that in Ubuntu 16.10 if one

background?

@Alberts, which distro are you using or which one is closest with
upstream flashback? Debian?

> P.S. Do you have numbers about usage?

I have somewhat exact numbers for Greece:
http://www.ltsp.org/stories/widget-map/?location=Greece
(less than half of the installations are shown in that map)

1000+ schools are using LTSP. They have on average one computer lab with 13 
computers, serving 100 students.
So 1000 installations, 13,000 computers, 100,000 users are using 
gnome-flashback 12.04 here.
We didn't upgrade to 14.04 because of issues with the keyboard layout and the 
indicator.
We'll upgrade them to 16.04 sometime this summer.
They don't show up in the official stats much (popcon, ubuntu repository hits 
etc) because there's only one installation per school, the rest of the 
computers are netbooted from a single image.

Worldwide I don't have exact numbers, the LTSP map is at
http://ltsp.org/stories/ but I suspect there are 10 times more
installations, but only half of them with gnome-flashback.

[Bug 1565640] Re: Set compositing-manager=false by default

2016-04-04 Thread Alkis Georgopoulos
@Alberts, I'll do some more tests and come up with hard numbers concerning the 
performance of metacity with or without compositing. I do believe that in some 
cases it will be possible to optimize the performance through appropriate bug 
reports and patches; but I also strongly believe that there will be other cases 
where the different design choices (compositing) will come with an unavoidable 
performance hit.
And while e.g. "3 times slower" may be acceptable in new e.g. core i5 systems, 
it's not acceptable in new e.g. atom systems. It doesn't affect only old PCs or 
networked X, it's just that it's more visible there.

@Dmitry and Alberts, what if LTSP users find it necessary to have compositing 
off by default? (as a local setting in their installations)
What issues should they expect from gnome-flashback then?
 - Harder window resizing due to 1 px border.
 - Notify-osd notifications ==> I did a quick test and they seem to work; 
albeit without transparency. Did I miss something?
 - Decorations ==> Example? I couldn't reproduce it.
 - Various docks ==> Example?

And more significant, how much support should they expect from gnome-flashback 
developers for the non-compositing case? For example, your support in all the 
bug reports that I've filed so far was excellent!
Does that mean that you won't be willing to do any non-compositing related work 
at all?
Would you be willing to guide persons that are interested in working on such 
issues? Or to accept patches from them?

I understand that gnome-flashback isn't specifically targeting old or networked 
clients, but does that also mean that it doesn't care at all about that use 
case?
If that's the verdict, then maybe LTSP should evaluate other desktop 
environments like Mate as the default (I think "marco" defaults to 
non-compositing in 16.04).

No matter the answer(s), I again want to thank you very much guys for
all your work! :)

[Bug 1551283] Re: ibus/im-config in Ubuntu GNOME

2016-03-08 Thread Alkis Georgopoulos
> ... I'll try to raise the issue in Debian's im-config, ... I will ask
that ibus isn't running in locales where it's not needed...

I installed Debian Stretch with the Gnome desktop environment and neither 
im-config nor ibus were installed by default there.
So I cannot report it in Debian, as it does make sense that if someone manually 
installs ibus, he'd want to have it running by default.

The problem is Ubuntu-specific, that people that don't need ibus have it
installed by default and running anyway.

Nevertheless, since ibus isn't running under gnome-flashback in non-cjkv 
locales, I'm not affected by that, so I can't complain.
Thanks again Gunnar, much appreciated! :)

About the "XDG_CURRENT_DESKTOP=Unity" part in gnome-flashback, it's caused by
unity-control-center/shell/control-center.c:
  g_setenv ("XDG_CURRENT_DESKTOP", "Unity", TRUE);

[Bug 1551283] Re: ibus/im-config in Ubuntu GNOME

2016-03-07 Thread Alkis Georgopoulos
Thank you very much Gunnar, the latest PPA changes work as expected for me in 
gnome-flashback, i.e. ibus isn't running and I can type Greek just fine.
What you have in the PPA is a good compromise for 16.04, please keep it that 
way.

For the future, post 16.04, I'll try to raise the issue in Debian's im-config, 
so that there's no need to have an Ubuntu debdiff (or to minimize it).
I.e. I will ask that ibus isn't running in locales where it's not needed, 
because:
1) It's causing issues (some of them will be solved in time)
2) It's wasting 20 MB of non-shared RAM (echo 3 > /proc/sys/vm/drop_caches; 
free; killall ibus-daemon; echo 3 > /proc/sys/vm/drop_caches; free), which is 
an issue in multi-user systems like LTSP thin clients.

2016-03-07 Thread Alkis Georgopoulos
Hi Gunnar,

> May I ask: Which display language are you using? If it's something
else but Greek, can you please switch to Greek, log out, log in again,
and then try to type in Greek (with IBus running). Does that make a
difference?

I tested with display language = Greek. I haven't tested with display
language = English.

> Also, just to make sure: Is your Xenial updated with the latest
package versions?

Yes.

> Well, it started with bug #1550325, where it was reported that some
applications need IBus to work. Maybe that's true for other flavors but
MATE. Then there is the inconsistency in Ubuntu GNOME, which led to the
confusion resulting in this bug report.

>From what I read there, some people reported that xim doesn't work for them.
Noone reported that ibus or xim are useful for people that don't need any input 
method at all.

> Nah, I don't think IBus requires a lot of memory. Please note that
IBus is running in Unity and Ubuntu GNOME, whatever the settings are.
(Only some environment variables differ.) I don't know about Gnome
Flashback in this respect.

I did report that ibus breaks the first Greek accented character in Unity as 
well.
Many people don't have the knowledge to pinpoint that ibus is what breaks their 
keyboard input, and just live with their problems.


Gunnar,
1) Would you be willing to accept a patch that makes im-config default to None 
in all desktop environments, in locales that don't need ibus or xim?
2) If not, is it possible to make language-selector-gnome NOT depend on 
im-config?
Or ubuntu-desktop not depend on language-selector-gnome?
Now we can't even uninstall im-config without uninstalling ubuntu-desktop, so 
we will have to resort to dpkg-divert to bypass this current issue... i.e. that 
16.04 will be the first LTS release that we won't be able to properly type in 
Greek, in all desktop environments.

[Bug 1551283] Re: "Region & Language" settings should allow you to set keyboard input method system

2016-03-06 Thread Alkis Georgopoulos
> With those changes, im-config (and gnome-language-selector) will
default to IBus in Ubuntu GNOME.

Hi, I've tested the packages from the PPA under Xenial's gnome-flashback, and 
now I got ibus running by default.
And it again breaks keyboard layout switching with the default Win+Space, so I 
can't type in Greek (LP: #1481025).

Why can't im-config default to ibus in locales that need it, and to None in 
locales that don't need it, as it did in previous Ubuntu releases?
Apart from the serious problems that it's causing, it's also wasting a lot of 
MB RAM per user, which is completely unacceptable for multi-user systems like 
LTSP.

Gnome-flashback isn't a flavor with a live CD etc, so it makes more sense to

If evolution-common is necessary for gnome-flashback, but evolution

[Bug 1492546] [NEW] Systemd runs ifdown on shutdown even when it shouldn't

2015-09-05 Thread Alkis Georgopoulos
Public bug reported:

The unit /lib/systemd/system/ifup@.service is Debian and Ubuntu specific, it's 
not part of upstream systemd.
On shutdown, it unconditionally ifdowns all interfaces:
  ExecStop=/sbin/ifdown %I

This is a regression from previous init systems (sysvinit and upstart)
which cared so that when a network file system was in use, they didn't
ifdown the interfaces.

Specifically, both /etc/init.d/networking and /etc/init/networking contain 
these functions:
  check_network_file_systems()
  check_network_swaps()
which output the message "not deconfiguring network interfaces: network file 
systems still mounted" and exit.

So, please call the same functions in the ExecStop= part of
ifup@.service.

[Bug 453605] Re: Make default mount umasks configurable

2015-01-17 Thread Alkis Georgopoulos
P.S. completely removing dmask from the mount options and letting 
/media/username "cover" the permission issues,
couples well with UDISKS_FILESYSTEM_SHARED,
so that people that want USB drives to be shared across users,
can just specify UDISKS_FILESYSTEM_SHARED="1" in udev for those drives.

Then /media/mountpoint will be world-readable for vfat/ntfs, as expected
(as opposed to /media/username/mountpoint which is protected with the default 
UDISKS_FILESYSTEM_SHARED="0").

[Bug 453605] Re: Make default mount umasks configurable

2015-01-17 Thread Alkis Georgopoulos
Quotting pitti from comment #2:
> We won't change the behaviour in udisks, there needs to be some default after 
> all.

Please completely remove dmask from the vfat/ntfs mount options, like fmask 
already is (absent).
Patch available at LP #482501.

I assume that dmask=0077 was added at some point in order to protect the 
contents of the mountpoint?
Nowadays, all user-mounted media is protected by the attributes of the parent 
directory, /media/username.
guest@pc:~$ ls /media/alkisg
ls: cannot open directory /media/alkisg: Permission denied

Inside /media/username/mountpoint, directories and files should be 
world-readable to behave better when copied elsewhere (LP #592748), e.g. in 
~/Documents, which is supposed to be world-readable by default.
For example, ~/.local is drwx-- but ~/.local/share is drwxr-xr-x,
similarly, /media/username should be drwx-- and 
/media/username/mountpoint/folders should be drwxr-xr-x.


For people needing a quick workaround, and since none exists yet, here's a 
really bad one that nevertheless does work for me:
# For the newer udisks2:
sudo sed 's/dmask=[0-9]\{4\}/dmask=0022/' -i /usr/lib/udisks2/udisksd
# For the older udisks:
sudo sed 's/dmask=[0-9]\{4\}/dmask=0022/' -i /usr/lib/udisks/udisks-daemon
# And reboot.

If udisks/udisks2 don't get fixed in some reasonable time, I'll upload
patches packages for the LTS Ubuntu releases in the Greek Schools PPA.
Unfortunately that'll be a pain, especially for udisks updates.

About configurability in nautilus, I don't think it will be needed if
dmask gets removed. And in any case configurability belongs in udisks,
not in packages that use udisks, because then every package that uses
udisks should provide such an option.

Thanks!

[Bug 1241284] Re: iBus has problem recognizing the keyboard shortcut

2014-03-02 Thread Alkis Georgopoulos
I uninstalled ibus and I still had the problem.
I think the Win+Space shortcut to change layouts is handled by 
gnome-settings-daemon, so I've put it in the Affects list.

I also think it's a bad idea to have a DE-specific way to change
keyboard layouts, because then we'd need to press e.g. Win+Space in
Gnome and Alt+Shift in a real console (vt), which is inconsistent...

gnome-settings-daemon should at least respect the xkb shortcut to change
keyboard layouts like it used to until now.

[Bug 1263591] Re: Add notification-area to panel-default-layout.layout

2014-03-01 Thread Alkis Georgopoulos
By old-style you mean XKB? And new-style is IBus?
IBus is too buggy, keyboard layout switching only works if one types slowly 
(LP: #1241284), and sometimes it doesn't work at all, and sometimes the 
indicator doesn't get updated even if you use the new-style switching, and it 
needs 40+ MB RAM for lower quality layout switching than the one X has been 
offering out of the box for ages...

We'll blacklist IBus for schools here as it's not yet usable, so
hopefully XKB will still be in a working state for 14.04.

Thank you for confirming LP #1260226! :)

I tried manually applying the patch for nm-applet, it works fine.
Pidgin works fine too, after playing a bit with its settings.
So yup notification-area isn't that important anymore.

Dmitry many gnome-panel bugs were fixed recently, thanks!

The only major blocker left for deploying 14.04 with gnome-panel now,
is the keyboard indicator not responding to xorg keyboard layout switches,
the rest issues left are either small ones or workarounds for them exist.

[Bug 1263591] Re: Add notification-area to panel-default-layout.layout

2014-02-28 Thread Alkis Georgopoulos
OK Dmitry and thank you for trying it,
but in my opinion if the ibus keyboard indicator is shown twice, that's an ibus 
bug and not a gnome-panel bug,
and it should be solved by making that setting default to false:

$ grep systray /etc/dconf/db/ibus.d/00-upstream-settings 
show-icon-on-systray=true

Also, none of those 2 keyboard indicators get updated when using the xorg 
combination to switch keyboard layouts,
so they should be removed anyway and be replaced by something that works before 
14.04 gets released,
it would be a major regression if the keyboard indicator is not working in an 
LTS release...

What I mean is that ibus bugs shouldn't affect this one.
That said, if nm-applet and pidgin get fixed for 14.04, notification-area isn't 
that important anymore...

For some reason `nautilus -n` didn't do it, but `killall nautilus;
nautilus` did the trick.

I.e. after the `killall nautilus` command, XDG_CURRENT_DESKTOP works
fine, I don't get a title bar when it's GNOME, and I do get the
traditional title bar when it's not GNOME.

So I clicked "affects me too" on LP: #1277963,

[Bug 1263591] Re: Add notification-area to panel-default-layout.layout

2014-01-24 Thread Alkis Georgopoulos
Thanks a lot for the feedback, I'm marking it as "Won't Fix" then.

Some notes:
1) nm-applet integration has issues, it doesn't display the applet for me on 
gnome-flashback without manually adding notification-area. I also tried with a 
recent 14.04 live CD, some times nm-applet did appear and some times it didn't, 
so I think there's some race condition involved, possibly related to LP 
#1256961. I'll test more when that bug is resolved. With notification-area 
manually added, there's no race condition, nm-applet always appears.

2) About pidgin, if you're talking about 
http://packages.ubuntu.com/indicator-status-provider-pidgin, I see there it's 
only available for 12.04, maybe that's why I didn't have the integration issues 
there and I'm having them now in 14.04.
In 14.04 I see that indicator-messages conflicts with 
indicator-status-provider-pidgin, is pidgin in 14.04 supposed to use 
indicator-messages, and for some reason it doesn't?

3) About stardict and the other apps that aren't yet ported to use the new 
indicators, let's hope they will soon, but until then, users have no way of 
knowing why some applications aren't displaying their indicators and that they 
need to add notification-area manually to work around that problem.
Deprecating something doesn't mean it has to be removed immediately, there 
should be a grace period until e.g. 80% of the involved applications has had 
enough time to update their code base to use the new indicators.
So maybe gnome-panel could grant them that grace period and add 
notification-area for a couple of more years, dunno...

Kind regards,
Alkis

[Bug 1263591] [NEW] Add notification-area to panel-default-layout.layout

2013-12-22 Thread Alkis Georgopoulos
Public bug reported:

Upstream gnome-panel includes notification-area:
https://git.gnome.org/browse/gnome-panel/plain/data/panel-default-layout.layout

In Ubuntu, debian/patches/01_layout.patch changes that file in order to make 
use of indicator-applet-complete. That patch is Ubuntu-specific, it doesn't 
exist in Debian:
http://anonscm.debian.org/viewvc/pkg-gnome/desktop/unstable/gnome-panel/debian/patches/

The problem is that that patch also removes notification-area, so
applications like pidgin, stardict etc (and even nm-applet in Trusty)
don't show up at all.

Please modify that patch so that notification-area is not removed, i.e.
add the following lines to it:

[Object notification-area]
object-iid=NotificationAreaAppletFactory::NotificationArea
toplevel-id=top-panel
pack-type=end
pack-index=1

I'm attaching an updated 41_classic_layout.patch.

2013-12-22 Thread Alkis Georgopoulos
I think this works around the problem:

sudo -i
echo '#!/bin/sh
/usr/bin/gnome-panel &' > /usr/local/bin/gnome-panel
chmod +x /usr/local/bin/gnome-panel

Logout or reboot, the panel should load quickly now.

In other words, it seems like something is waiting for gnome-panel to
finish loading, and if it's put in the background, then everything goes
fast again and the panel itself loads quickly...

[Bug 580961] Re: unzip fails to deal correctly with filename encodings

2013-11-07 Thread Alkis Georgopoulos
Thanks, that partially solves the problem (Precise, 6.0-4ubuntu2).

The question marks are gone, so LP: #1199239 can be marked 'Fix released'.
This (LP: #580961) bug is NOT fully addressed though.
The problem that remains is that only a few codepages are supported.

For example, unzipping a file that contains Greek (cp737) filenames doesn't 
work out of the box:
$ unzip -l biografiko.zip
biografiko/ОЫЮЪхЬк ймгзвуирйЮк ШхлЮйЮк_Щ.doc (wrong codepage)

On the other hand, if someone manually specifies the codepage, it does work:
$ unzip -O cp737 -l biografiko.zip
biografiko/Οδηγίες συμπλήρωσης αίτησης_β.doc (right codepage)

I'm guessing it would work if we added this line:
+{ "CP1253", "CP737" },
...in the mapping table defined in debian/patches/06-unzip60-alt-iconv-utf8:

+/* A mapping of local <-> archive charsets used by default to convert filenames
+ * of DOS/Windows Zip archives. Currently very basic. */
+static CHARSET_MAP dos_charset_map[] = {
+{ "ANSI_X3.4-1968", "CP850" },
+{ "ISO-8859-1", "CP850" },
+{ "CP1252", "CP850" },
+{ "UTF-8", "CP866" },
+{ "KOI8-R", "CP866" },
+{ "KOI8-U", "CP866" },
+{ "ISO-8859-5", "CP866" }
+};


I'm not changing the verification-needed flag because it's only partially fixed,
which might mean "verification-failed, affected people do list your codepages 
here so that we add them to the mapping table before we upload this to 
-updates",
or it might mean "verification-done and open a new bug report for adding more 
codepages",
your call. Thanks!

[Bug 1078679] Re: Gnome fallback - intermittent menus on top panel

2012-12-29 Thread Alkis Georgopoulos
Here's a script that makes gnome-panel try twice to get loaded properly,
so it should avoid the need for a desktop launcher that kills the panel
for most of the cases; for the few that will remain, a logout/login
should suffice...

Greek teachers shouldn't apply it, it'll come as an update from our
ts.sch.gr PPA.

Create /opt/ltsp/i386/usr/local/bin/gnome-panel, with the following
contents:

#!/bin/sh

if [ "$LTSP_FATCLIENT" != "True" ]; then
exec /usr/bin/gnome-panel "$@"
fi

/usr/bin/gnome-panel "$@" &
sleep 10
if ! pgrep -nx indicator-sound -U $USER >/dev/null 2>&1; then
echo "$(date) - restarting gnome-panel" >> $HOME/.xsession-errors
exec /usr/bin/gnome-panel --replace
fi


And just a bit more debugging info, in case anyone's interested:
* On a client that has the problem, the gnome-panel process is there, but all 
the applet processes (e.g. indicator-sound-service) aren't.

* The .xsession-errors of a client that doesn't have the problem, contains:
Initializing nautilus-gdu extension
** Message: applet now removed from the notification area
** Message: using fallback from indicator to GtkStatusIcon
** Message: moving back from GtkStatusIcon to indicator
...while on a client that does have the problem, the last line is missing (i.e. 
it hangs somewhere between outputing those 2 lines)

* I tried removing everything from /etc/xdg/autostart, except for gnome-
settings-daemon.desktop, and the problem did appear to become more rare,
but eventually it did happen again on 1 client after rebooting 10
clients 6 times (while usually it happens on 1 out of 10 clients, every
time).

Προειδοποίηση διαχειριστή παραθύρων: Άκυρο WM_TRANSIENT_FOR παράθυρο 0x3a1

The first line translates to "window manager warning",
and the second one to "window manager warning: cancelled WM_TRANSIENT_FOR 
window 0x3a1 that was defined for  0x3a3 (No nam...)"

gnome-panel --replace did _not_ work the first time, it resulted in the same 
non-functioning panel without menus,
but it worked fine the second time I ran it.

I should also note that LTSP fat clients are using SSHFS, just in case someone 
finds out it's related to file locking or something.
We weren't experiencing it in 10.04 with NFS /home (300 schools, worked fine 
for 2 years), but that was Gnome 2 though.

[Bug 491940] Re: Patch for LTSP clients to properly reboot/shutdown

2012-09-14 Thread Alkis Georgopoulos
Since the proposed patch was not accepted by the Ubuntu devs that
maintain gnome-session, nor any alternative component was suggested to
try to patch that instead, we didn't upload a patched gnome-session in
the ts.sch.gr PPA for 12.04, it's only there for 10.04. So no point in
adding the PPA in 12.04, it doesn't help with this problem.

We've developed Epoptes instead, which can shut down the LTSP clients in
any Desktop Environment.

If upstream Gnome and Gnobuntu don't deprecate gnome-fallback, we'll try
to send a patch there, otherwise Gnome will be unusable with LTSP in the
future anyway, at least for thin clients (3d/llvmpipe over the network
is extremely slow, and Unity-2D support was dropped). So maybe LTSP in
the future will propose XFCE/LXDE instead of Gnome.

[Bug 915468] Re: the unity-greeter keyboard's selection doesn't respect the user config

2012-09-13 Thread Alkis Georgopoulos
This is still an issue in Ubuntu Precise fully updated.

1) If I use autologin, everything is fine, my keyboard layout is the same as 
the system default, En/El.
2) If I use the greeter:
 * I only have "En" available in the greeter,
 * I only have "En" available in the session,
 * I don't get a keyboard layout panel applet in the session.

Steps to reproduce:
mkdir /tmp/etc
sshfs localhost:/etc /tmp/etc
nautilus /tmp/etc
=> double click on "adduser.conf"

Nautilus prompts:
Do you want to run "adduser.conf", or display its contents?
"adduser.conf" is an executable text file.
[Run in Terminal] [Display] [Cancel] [Run]

Of course the "adduser.conf" permissions are fine in the file system and
in the sshfs mount, it's not executable.

"assignee: madlokil" means that madlokil is the developer responsible for 
fixing the bug.
"status: In progress" by thefusionite means that someone is working to fix the 
bug, so the other developers don't need to bother with it.
So by setting the status to assigned+in progress, you actually discourage 
developers from working on this bug.
Allow me to assume that it was done by mistake, and to reset the status to 
"unassigned" and "triaged".


WRT comments #96 and 97, since the newer unzip version is not yet packaged for 
Debian, and doesn't look like it will be in time for Precise, could we do 
something so that we don't have a broken unzip in the next LTS version too?
 * Either package the newer upstream version,
 * Or check what's missing from the existing patch that prevents -I and -O from 
working?

[Bug 491940] Re: Patch for LTSP clients to properly reboot/shutdown

2011-07-06 Thread Alkis Georgopoulos
Sorry, no idea. We're using only LTS releases here, and I'm kinda
pressed time-wise this year, so I won't be able to test with recent
versions of the involved packages until Ubuntu 12.04, if it's still a
problem then.

The LTSP task mainly referred to LTSP_LOGOUT_ACTION (commit
http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-
trunk/revision/1481), so yeah, either invalid or committed will do,
until gnome-session can  provide a method to notify the caller (LDM,
xinit...) about the selected action (logout, reboot, shutdown).

Another approach is to at least make indicator-session policy-kit aware, so 
that it doesn't display the reboot/shutdown menu items at all:
https://bugs.launchpad.net/ubuntu/+source/indicator-session/+bug/474392

>From a user's perspective, that's not as good as fixing gnome-session,
because then the user loses logout/reboot/shutdown functionality from
the menus.

That person closed my bug report (LP #477755) where I was suggesting the 
altlinux solution that was finally accepted upstream, in order to open this 
bug. Then he told me that comments in this bug report were unwelcome (comment 
#16), so I became unable to provide feedback to the bug I reported.
Then he started asking people money about his packaging job in libnatspec 
(developed by Vitaly Lipatov) and being rude when people weren't willing to pay.
Fortunately at a point he got "insulted" because people continued to comment on 
this bug report, and left.

What I mean is that I don't want to contact that package maintainer, and if 
possible, I wouldn't want to use his package either, more so when the upstream 
solution doesn't use it.
I've been coding open source programs for almost 20 years now, and been 
packaging some of them in the last few years that I've switched to Linux. I'd 
prefer to redo any needed coding or packaging work myself before having to 
cooperate with such a person.

For now I'll just wait for Debian to package the newer version of unzip,
and then contact upstream if any problems persist.

It correctly detects the WIN encoding, which is CP1253, but it doesn't 
correctly detect the DOS encoding.
It claims it to be 437, while the correct one is 737:

No, the -I and -O options do not work properly.
It looks like something, maybe just a couple of lines, were missing from the 
Natty patch.

I described the current situation in comment #89:
 * Extracting works: UNZIP="-o cp737" unzip archive.zip
 * Listing doesn't: UNZIP="-o cp737" unzip -l archive.zip
Since listing doesn't work, file-roller also doesn't work (it uses `unzip 
-ZTs`, i.e. listing in zipinfo mode).


And no, I'm not talking about autodetection, libnatspec wasn't used in the 
upstream patch and it fails to autodetect Greek anyway (haven't tested other 
locales).
So personally for now I'd be happy if unzip was at least working with the -I 
and -O options and with the UNZIP environment variable.

I just tried frol's PPA with the libnatspec dependency.
It didn't correctly autodetect the encoding so I didn't see any benefit with 
that implementation.
It did however work as good as unzip did in older Ubuntu versions, i.e. both 
extracting *and listing* worked if either the UNZIP/ZIPINFO environment 
variables were defined, or if the -O parameter was used:

# autodetection doesn't work:
$ echo $LANG

# (alternatively, the same output is also produced with "-O cp737" in the

# and in zipinfo mode, as called by file-roller:
$ ZIPINFO='-O cp737' unzip -ZTs biografiko.zip

# (alternatively, the same output is also produced with "-O cp737" in the 
command line)


So, it looks like only half of the required patch was included in unzip 
6.0-4ubuntu1.
Please make listing (unzip -l and unzip -ZTs) work, as it did in previous 
Ubuntu versions.

[Bug 580961] Re: unzip fails to deal correctly with filename encodings

2011-02-14 Thread Alkis Georgopoulos
I confirm that 6.0-4ubuntu1 is still half-broken, compared to previous Ubuntu 
versions.
 * Extracting works: UNZIP="-o cp737" unzip archive.zip
 * Listing  doesn't: UNZIP="-o cp737" unzip -l archive.zip
Since listing doesn't work, file-roller also doesn't work.
I tested with 
http://www.ops.gr/Ergorama/fileUploads/ypiresiaops/prokirikseis/biografiko.zip


Btw, here's an easy way to provide the unzip environment variables for all 
users.

Create the following script:
$ sudo gedit /usr/local/bin/unzip

Paste these 4 lines, but replace cp737 with the appropriate charset for your 
locale:
#!/bin/sh

export UNZIP="-O cp737"
export ZIPINFO="-O cp737"
exec /usr/bin/unzip "$@"

Save, exit, and make the script executable:
$ sudo chmod +x /usr/local/bin/unzip

Runs fine on my i386 Lucid:

$ dpkg-query -W gdm
gdm 2.30.2.is.2.30.0-0ubuntu5

Connected via XDMCP about 10 times in a row with no problems.
