Part of the problem could be that that Nautilus eats up a lot of memory (even 
up to the point where it may crash) and may slow down or freeze when copying 
many files. This is due to issues with gvfs:

2017-08-02 Thread levien
This is most probably caused by this upstream issue: 
https://bugzilla.gnome.org/show_bug.cgi?id=757747

These patches to gvfs should greatly reduce the problem:
https://git.gnome.org/browse/gvfs/commit/?id=0e001c9
https://git.gnome.org/browse/gvfs/commit/?id=fe33512
https://git.gnome.org/browse/gvfs/commit/?id=1224147
https://git.gnome.org/browse/gvfs/commit/?id=57acc80

As I understand, gvfs >1.30.3 should include these patches,
so Ubuntu Zesty 17.04 should suffer much less from this issue.
Can someone verify this?

There are several similar bug reports that may be duplicates:

[Bug 1574211] Re: The "nolapic" boot option causes a kernel panic

2016-05-14 Thread levien
I tested the mainline kernel 4.6.0-040600rc7, and the problem does not
occur with this version. I also tested 4.4.10-040410, in which the
problem did occur. It seems that the problem is indeed fixed in the
upstream 4.6 kernel series, but not in 4.4.

** Tags added: kernel-fixed-upstream

** Changed in: linux (Ubuntu)
   Status: Incomplete => Confirmed

** Description changed:

  The kernel parameter "nolapic" causes an unrecoverable kernel panic with
  the 4.4.0-21 kernel in Xenial (16.04). I've verified this on two
  different machines. The 4.2.0-36 kernel from 15.10 boots without
  problems, with the same options. The kernel-logs contain no information
  on the failed boot attempts.

[Bug 112310] Re: Setting Wacom pen button to double click doesn't work

2013-04-17 Thread levien
This seems to be fixed in 12.04, albeit with a new syntax. To assign a
double-click to a button, either run something like:

xsetwacom --set "Wacom Graphire2 4x5 stylus" Button 3 "button 1 button
1"

(source: https://gist.github.com/i-e-b/2894651)

or better, create a file /usr/lib/X11/xorg.conf.d/10-wacom.conf with the
following line:

Option "Button 3" "button 1 button 1"

This fixes the problem for me.

As a reasonable temporary workaround in Lucid, I downloaded the latest version 
of latex.xml from svn 
(http://websvn.kde.org/trunk/KDE/kdelibs/kate/syntax/data/latex.xml?view=markup)
 and copied it into ~/.kde/share/apps/katepart/syntax/
It still has trouble with macro-parameters and backward quotes, but at least 
most LaTeX commands will be properly recognised as such. Especially if you only

Currently the best way around this is not to use the oss4-dkms package

[Bug 581663] [NEW] Wacom stylus buttons no longer emit double click events in Xorg

2010-05-17 Thread levien
Public bug reported:

Binary package hint: xorg

This issue has already been reported for Jaunty in bug #112310, but as
requested I'm submitting a new bug report for Lucid.

According to the documentation from the Linux Wacom Project, you should
be able to set a Wacom stylus button to double click using either a
command like:

xsetwacom set "Wacom Graphire2 4x5" button3 "dblclick 1"

or by adding a line to the appropriate section of xorg.conf (or in
Lucid: /usr/lib/X11/xorg.conf.d/10-wacom.conf):

Option "Button3" "dblclick 1"

The latter method stopped working in Ubuntu 7.04, and the former method
stopped working in Ubuntu 9.04. Both methods still do not work in 10.04.
The first method will not produce any errors, but seems to have no
effect when using a "dblclick" setting. The second method will produce a

A workaround to get double click events working has been reported, but
it bypasses the Wacom problem (by changing the X key bindings) and I

Good work, the patched package from the PPA seems to install without

[Bug 112310] Re: Setting Wacom pen button to double click doesn't work

2010-05-06 Thread levien
As suggested in bug #446943 I added the following two lines to the first
section of /usr/lib/X11/xorg.conf.d/10-wacom.conf in Lucid:

Option "Button2" "3"
Option "Button3" "dblclick 1"

Button 2 now works as expected, but for button 3 Xorg still complains that the 
value should be an integer and refuses to work. When using the values 196609 or 
17 Xorg does not complain, but double click events also don't work.
When using xsetwacom no errors are logged, but again the double click event is 
not emitted.

I also tested the xsetwacom method without compiz, but the result was
the same. Also with Metacity I could not get double click events to
work...

The problem still persists in Lucid when using xsetwacom. Also, I'm
unsure as to where the wacom configuration settings should go now in the
Xorg configuration files... The HAL fdi-stuff is deprecated as I
understand, and wacom configuration now seems to be located in
/usr/lib/X11/xorg.conf.d/10-wacom.conf. However, it contains InputClass
sections rather than the old InputDevice sections. I have trouble
finding any documentation on this new configuration, and don't want to
break Xorg by messing around with it unknowlingly. Can anyone enlighten
me? :-)

I can confirm this on Jaunty. In Intrepid, this at least used to work:

xsetwacom set "Wacom Graphire2 4x5" button3 "dblclick 1"

But as of Jaunty, setting a button to "dblclick 1" or "17" seems to be
broken, which is rather annoying. I haven't tried setting it in
xorg.conf, as that already stopped working in Hardy. Moreover, Wacom
tablets are now recognised through hald anyway (making them
hotpluggable, which is nice).

2009-03-10 Thread levien
*** This bug is a duplicate of bug 269904 ***
https://bugs.launchpad.net/bugs/269904

Not exactly, as explained by nVidia developer Aaron Plattner in
https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/269904/comments/33
it is a design problem in X itself. More precisely, the problem is in
the XDamage extension, which notifies applications and other parts of X
when the screen needs to be redrawn. It was apparently never designed to
handle asynchronous rendering (as Compiz does with the nvidia driver).
This can result in redraw requests being sent/received in the wrong
order. The Damage extension needs to be extended to fix this, which is
not exactly trivial. That's why this is all taking so long...

[Bug 269904] Re: Screen refresh problems with nvidia on intrepid

2009-02-12 Thread levien

I've been trying to track down the cause of this problem for ages, and I think 
the comment from another user at bug #270377 has just helped me find it. 

Apparently the redraw problems described here and in the other bug
reports are caused by a race condition, that can occur with compiz in
combination with nvidia driver versions above 177.76. According to
nvidia developers at the nvnews forums: "[the cause of the problem] is a
race condition between the X server and compiz that's the result of a
fundamental design problem in the way the Damage extension works." and
"[fixing it] will require more changes to the Damage and GLX extensions,
the X server, Compiz, and the NVIDIA X driver."

Because it is apparently caused by a design problem, it will probably
take some time before the problem is fixed. The only real way to ensure
it doesn't happen at the moment is not to use compiz. But on some
systems it helps to change settings that affect the timing of pixmap
uploads to the GPU. That's why it may help to disable the compiz
"--loose-binding" option, or to play with the powermizer settings.

The fact that the occurrence of race-conditions may be affected by
timing also explains the fact that everyone seems to experience this bug
(and its many duplicates) differently, depending on hardware-
configuration, which programs are running, the number of open windows,
X.org and driver settings, etc.

For me, restarting compiz without loose binding immediately solved the
refresh problems, albeit at the cost of compiz rendering performance. I
just had a look at the wrapper script that launches compiz in Ubuntu. It
enables --loose-binding on nvidia hardware (which in turn works around a
performance issue with texture binding on nVidia cards), but it only
seems to do this when indirect rendering is disabled (the default
setting). So in theory this should disable --loose-binding without
having to edit the wrapper script or (re)start compiz by hand every
time:

mkdir -p ~/.config/compiz; echo INDIRECT=0 >> ~/.config/compiz/compiz-
manager

It just adds "INDIRECT=0" to the configuration file ~/.config/compiz
/compiz-manager, to force indirect rendering. This will of course
degrade performance (e.g. with desktop cube) and will also disable some
effect plugins (e.g. water). But I much prefer it to having the current
redraw problems or disabling desktop effects all together.

I do hope this issue gets properly fixed though...

[Bug 270377] Re: content of window do not redraw automatically (intrepid)

2009-02-07 Thread levien
I just tried the 180.27 nvidia driver as well, but this version still
locks up my system after an hour or so. When this happens the Xorg
process goes to 100% CPU use, and I need to log in remotely to either
kill X or restart the system, because other methods (CTRL-ALT-DEL, CTRL-
ALT-Backspace or switching to a text terminal) don't work anymore...
Unfortunately the system logs don't give any indication of errors when
this happens. I've switched back to 177.82 again, because at least this
version is stable (for me).

Also, the 180.27 driver still gave redraw issues. Here's slightly more
detailed description: With compiz 0.7.8 all window updates would cease
at the moment any application tries to go fullscreen (screensaver, image
viewers, etc.). After I upgraded to compiz 0.7.9, at least this problem
was gone and the redraw-issues were relatively minor and infrequent (or
unpredictable if you will), and mostly occured in Firefox (haven't tried
LastFM). However, when I open a lot of (I think more than 32) windows,
the contents of the most recently opened windows isn't drawn or updated
at all until I manually resize the window.

My system has an Asus M3N 78 motherboard with a GeForce 8200 mGPU and a
quad-core Phenom CPU. When I turn off desktop effects, everything works
just fine. (To be able to switch easily I installed Compiz-Switch:
http://forlong.blogage.de/article/pages/Compiz-Switch). I guess I'll
just have to keep trying new versions of the nvidia driver as they are
released...

I experienced more or less the same redraw issues, on an up-to-date
Intrepid AMD64 install with a GeForce 8200. The failures to redraw
window contents occur only with desktop-effects turned on, and mostly in
Firefox but sometimes also in other applications. I tried both the
standard 177.82 and the new 180.22 nvidia drivers, but both experienced
redraw problems. Additionally, the 180.22 driver destabilised USB and
X.org on my system (interrupt issues?), so I had to switch back to 177.
Next I tried updating compiz to 0.7.9-git20080918. This seems to have
helped a bit, I now only get redraw issues after opening a lot of
windows (>32). If I keep the number of open windows below 32, everything
seems to be OK. Strange...

The compiz redraw-problems seem to pop up every time an application

my case, but I also get the same issues when I try to view a full-screen
image. So it seems to be the same problem that is described here:
http://www.nvnews.net/vbulletin/showthread.php?t=122336

Reverting to version 173 of the nvidia driver seemed to resolve this particular 
issue for me, although I didn't test very well because this driver messed up 
scrolling in most applications, making it impossible to work. Updating the 
nvidia driver to the current stable release (180.22, taken from 
https://launchpad.net/%7Emythbuntu-trunk-0.22/+archive/ppa) also seemed to 
solve the problem, but caused stability issues on my system. (These were 
possibly interrupt-related, after a while my USB devices tended to lock up, or 
the entire X.org just crashed or hung for no apparent reason.) 
So I switched back to the default 177.82 nvidia driver and upgraded compiz to 
the latest git-snapshot (0.7.9-git20080918, following 
http://ubuntuforums.org/showthread.php?t=971379). This seems to cause the least 
problems so far. There are still some annoying window-update issues when I open 
a lot of windows, but other than that everything works as it should with 
desktop-effects switched on.

I guess this bug is a combined problem of the current compiz-fusion
(0.7.8) and the nvidia 177.82 driver in Intrepid, as updating either
seems to make it go away...

[Bug 225858] Re: compiz refreshes infrequently and doesn't redraw window contents after suspend/resume.

2009-01-23 Thread levien
I get the same problems on my system, a quad-core AMD Phenom with an
nVidia GeForce 8200 (rev a2) chipset, running Intrepid Ibex 8.10 amd64
and  version 177 of the nvidia driver.

Additional information:
The problems also seem to occur after the screen has just been blanked by the 
(default) screensaver, without going to standby or suspend (also the monitor 
stays on). After coming back from the screensaver, redraws and effects are slow 
as hell, and window contents is no longer updated properly. Events such as 
mouseclicks and keyboard input continue to be registered by applications, but 
because nothing is updated it appears as though the system hangs. Switching off 
desktop effects or restarting compiz.real restores behaviour back to normal.

At first I thought it was caused by the Wobbly Windows plugin, because
after disabling the plugin everything seemed to work fine again.
However, this was only temporary because after the next screensaver
blank the problems returned, though in a slightly different way (redraws
only failed for newly opened windows this time). Changing other plugin
settings did not seem to help.

There were no errors reported in the Xorg logfile or in /var/log/messages.
I haven't tried reverting to version 173 of the nvidia driver yet.

[Bug 24630] Re: Evince crashes when zooming PDF-File to 400%

2008-09-08 Thread levien
I have been experiencing possibly the same problem with evince and any
PDF-file which has scanned pages (e.g. any scientific article from
before 1995 or so, such as this one:
http://www.pubmedcentral.nih.gov/picrender.fcgi?artid=1215979&blobtype=pdf
)

These documents seem to open just fine at first, but then the system
just locks up swapping and eventually evince is killed due to lack of
resources. Zooming to 400% is not even needed. Monitoring with top shows
that the evince process fills up all available memory, followed by all
available swap space, until it is killed.

I'm using evince on an up-to-date 8.04 Hardy Heron system with 512 Mb
memory and 512 Mb swapspace. The same documents open fine with KPDF and
acroread on the same system, and with evince on a Feisty system. PDF
documents without scanned pages seem to open just fine in evince as
well.

[Bug 112310] Re: Setting Wacom pen button to double click doesn't work

2008-04-26 Thread levien
Sorry for the delay, I only just installed Hardy due to lack of time (and 
disk-space for the update).
The wacom-tools method seems to work correctly now. However, adding 

Option "Button3" "dblclick 1"

or

Option "Button3" "17"

to xorg.conf still does not work. When using the first form, X complains
that the parameter value has to be numeric. However, the old numeric
value 17 also does not work anymore. Seems as if the driver and the bit
that parses the Xorg values are out of sync somehow, one expecting a
numeric value while the other expects a string...

As a workaround, I've added the following command to my Session:

xsetwacom set stylus button3 "dblclick 1"

Where should I report the xorg.conf issue?

-L.

[Bug 211962] [NEW] keyjnote exits with OpenGL error

2008-04-04 Thread levien
Public bug reported:

Binary package hint: keyjnote

I'm trying to run keyjnote on the most current Ubuntu server 8.04 beta.
Xorg is running fine, Xpdf works fine, glxinfo reports a working GL
environment (albeit software rendering), glxgears runs fine, yet
keyjnote always gives me the following error:

It seems that python cannot find the OpenGL library, but I don't know
anything about Python so I'm having a hard time figuring out what's
causing this...

[Bug 112310] Re: Setting pen button to double click doesn't work

2007-08-13 Thread levien
I have the same problem, but with a Graphire tablet. I tried both:

xsetwacom set stylus button3 "dblclick 1"

and setting it in xorg.conf:

Section "InputDevice"
Driver  "wacom" 
Identifier  "stylus"
Option  "Device""/dev/input/wacom"
Option  "Type"  "stylus"
Option  "Button2"   "3"
Option  "Button3"   "dblclick 1"
EndSection

So it seems that this bug is not related to xsetwacom but to the wacom-
driver that is shipped with Xorg...

-Levien

** Also affects: xorg (Ubuntu)
   Importance: Undecided
   Status: New

** Summary changed:

- Setting pen button to double click doesn't work
+ Setting Wacom pen button to double click doesn't work

** Description changed:

  Binary package hint: wacom-tools
  
  I have a Wacom Volito 2 and am using Ubuntu 7.04. In both 6.06 en 6.10 I
  was able to set the second button of my Wacom pen to doubleclick using
  the following code in xorg.conf:
  
  Option"Button2""17"
  
  However, this code doesn't work anymore in Ubuntu 7.04. Using 'xsetwacom
  list param" I found out that I had to use the following code in the
  console to set my stylus to doubleclick:
  
- xsetwacom stylus Button2 "dblclick 1"
+ xsetwacom set stylus Button2 "dblclick 1"
  
  But that doens't work... also the following codes don't work:
  
- xsetwacom stylus Button2 "dblclick 0"
- xsetwacom stylus Button2 "dblclick 1"
- xsetwacom stylus Button2 "dblclick 2"
- xsetwacom stylus Button2 "2"
- xsetwacom stylus Button2 "17"
+ xsetwacom set stylus Button2 "dblclick 0"
+ xsetwacom set stylus Button2 "dblclick 1"
+ xsetwacom set stylus Button2 "dblclick 2"
+ xsetwacom set stylus Button2 "2"
+ xsetwacom set stylus Button2 "17"
  
  I hope this can be fixed, since a single button for doubleclicking is
  way easier than tapping twice or tapping once and using the return
  button.

[Bug 15093] Re: gksudo fails if using libpam-krb5 for password auth

2007-06-20 Thread levien
Hi Eddie,

Well, I'm no expert on this I'm afraid. But as far as I understand it
the problem is as follows: gksudo is basically a graphical front-end for
sudo, and therefore it needs to know when sudo asks for a password. PAM
modules however present their own prompt, which may be quite different
from the standard "Password:" one. If that happens, gksudo will not
recognise the custom password prompt and will just keep waiting. The
first patch just tells sudo to override the PAM prompt in such cases, so
that gksudo will recognise it. The problem is that this breaks certain
kinds of authentication (which of course is not a problem if you don't
need those, as in my case). The second patch adds an option to sudo
allowing for a postfix-string to be appended to the password prompt.
gksudo can then simply wait for this string, and then pass its password
to sudo. However, this patch is still waiting to be included in sudo. As
it has been submitted in two years ago, it seems that the sudo
developers do not consider it to be a priority feature.

So in short, the problem with gksudo and pam is not really a bug, it is
just a result of the way gksudo is implemented as a front-end to sudo.
The best way to get it fixed would be to let the sudo maintainers know
that this is really a feature that people do need, and to help them test
it. Here is sudo bugzilla link again:
http://www.sudo.ws/bugs/show_bug.cgi?id=180

As for your problem, the patched version of sudo may or may not solve
it. It probably depends on what kind of prompt the bioapi module
presents, if any. I wouldn't be too worried about patching sudo though.
You can easily see what the patch does just by looking at the code.
Furthermore, you can always go back to the original sudo if it doesn't
work. The only problem is that the link to the patched version will
probably get overwritten if sudo is updated...

Best regards,
Levien

[Bug 15093] Re: gksudo fails if using libpam-krb5 for password auth

2007-06-06 Thread levien
Have you tried a patched version of sudo? You can get Jeff's patch from 
http://www.sudo.ws/bugs/attachment.cgi?id=37 
Get the source-package for sudo ("apt-get source sudo" or the latest tarball 
from http://www.sudo.ws/sudo/download.html), apply the patch, recompile and 
install (e.g. in /usr/local). You can rename the original sudo (in /usr/bin) to 
something like /usr/bin/sudo_original and then do "ln -s /usr/local/bin/sudo 
/usr/bin/sudo". That might solve your problem for the time being.. Of course 
this issue really needs to be addressed by Ubuntu / gksudo / sudo if more 
people are to use PAM authentication with Ubuntu.

2007-04-20 Thread levien
I agree with brettatoms, it is important to fix this issue if Ubuntu is
to be usable in anything other than a stand-alone desktop environment. I
am currently working with a small NGO to try and replace their ancient
Windows 98 installations with Ubuntu 7.04. We authenticate the Ubuntu
machines against a windows domain server. I now work around this bug by
installing a patched copy of sudo in /usr/local/bin, and replacing
/usr/bin/sudo with a symlink to the patched version. But anyone will
agree that this is hardly an elegant solution...
