[Bug 1325899] Re: evince is excruciatingly slow on some documents

2015-12-12 Thread cro
This appears to have been regressed somewhere. 15.04 with libpoppler
0.30 - a PDF that used to render instantly (and renders instantly using
muPDF) now takes on average 10-15s to render a single page using Evince
or Atril, or longer if focus is missing.

As the behaviour is the same in both Evince and Atril, my assumption is
that the issue is in poppler somewhere - PDF renderers that do not use
poppler are ultrafast, those that use it are ultra slow.

[Bug 1525526] [NEW] evince/atril is excruciatingly slow

2015-12-12 Thread cro
Public bug reported:

For image-heavy PDF files, both Atril and Evince are extremely slow when
rendering the page. 'Slow' being in the region of 5-30s (timed),
depending on the page, and depending on focus.

Thumbnails take an equally long time to render.

The same PDF files opened in muPDF render pages instantly.

Currently version of libpoppler is 0.30.0-0ubuntu1.

[Bug 1432171] Re: [udev] Shows starting version 219 boot message even with quiet

2015-04-27 Thread cro
Well, I resolved the error  - by installing `upstart-sys` (which
replaces `systemd` with upstart)

So it appears this is an issue where the removal of `upstart` breaks
startup of some display managers and prevents the running of login
scripts. The workaround is to manually start your chosen display manager
from a cli.

Reconfiguring (dpkg-reconfigure) doesn't work, and on this basis, `mdm`
works, `lightdm` crashes to low-graphics mode and `sddm` (if manually
installed) shows a plain white screen.

So no, it's not related to `sddm`, it is directly related to the
implementation and use of `systemd` as a replacement to `upstart`.

It may or may not be cosmetic (the display of the message) but the
overall effect of installing systemd in this instance has the net result
of causing user systems to fail to boot into a graphical display
manager, without a relevant or informative notice.

So, if you see starting version 219 and your display manager (login
window) doesn't run, but you *can* load it by manually starting it form
the console, you most likely have a problem with your display manager
startup script(s). Either replace the display manager startup scripts to
work with `systemd`, or remove `systemd` and replace it with `upstart-
sys`.

I  get this error as well, and I do NOT have sddm installed, so the

by waiting, I don't have quiet enabled and I'm using mdm.

The only way to boot is to switch to another tty (F1 - the only one
available) and execute sudo mdm restart manually.

This is a critical error, not a trivial one, as i has completely broken
the boot process on my laptop.

[Bug 1152736] Re: system swapping itself to death in raring for no good reason

2013-06-15 Thread cro
I disabled tmpfs when I started seeing this issue, however the swapping
has continued, albeit with a lesser number of issues - until today, when
the swapping issue was so bad that I performed a hard power down after
my laptop had been unresponsive for 24 minutes (clock showed 14:32, I
forced a power-down at 14:56).

I couldn't log into any other TTY (it would time out after 60 seconds,
or not respond at all), so I couldn't access top or free or anything to
try and debug this issue, or even force-kill firefox (which usually
solves the problem).

I didn't have many windows open, although I was doing some web
development at the time (perhaps 3 or 4 firefox windows, Eclipse, MySQL
workbench).

I am also seeing instances where swap is using 3Gb, cache is using
1Gb, and there are no processes running (default desktop only - all
other processes/applications stopped). The only way to force the system
to stop using swap when there is nothing to swap is to do a hard
restart.

Time to also tune background processes I think - the system uses more
than 3Gb of physical RAM when idling.

I commented out this:

I added this: 
rmmod rts5139 (this is the smart card reader poller)

I've not had a swap to death instance since that wasn't directly related
to too many embedded objects on a Firefox page. There's been some
swapping going on, and some general slowdowns, but nothing like the past

It may be coincidence though.

2013-05-20 Thread cro
An update.

The swappiness is still killing my laptop. It seems to be explicitly
related to having Firefox running, especially if I have multiple windows
open, with lots of content.

Killing the Firefox process solves the swap problem and returns control
of the desktop and mouse, and allows me to continue working.

Here's my 'free' status when kswapd0 is using 100% CPU. In this
situation kswapd0 is using between 90 and 120% CPU according to `top`,
and everything else is under 5%, including firefox.

cro@zen:~$ free -h
 total   used   free sharedbuffers cached
Mem:  3.8G   3.3G   503M 0B16M   1.4G
-/+ buffers/cache:   1.8G   1.9G
Swap: 3.9G   274M   3.6G

Or, because text formatting is bad, of 4Gb swap, 3.6Gb is free, and I
have 500Mb of free RAM.

vm_swappiness is set to 0.

This happens to me on average more than once an hour when I'm working
(multiple windows/tabs open).

Nope, I'm not using LVM snapshots. I'm thinking it's something to do
with embeds or media objects - further attempting to work today showed
that whenever the flashplugin was loaded (in either firefox or chrome,

were killed.

I'm doing more testing/tweaking myself, things like disabling SDD

[Bug 1152736] Re: system swapping itself to death in raring for no good reason

2013-05-01 Thread cro
This bug affects my laptop as well, regardless of swap or swappiness
settings.

The laptop is an Asus UX32A, and has only ever had 13.04 installed (from
the RC prior to release)

/swap is configured with 4G of space on the internal SSD rather than the
HDD.

Under normal usage kswapd0 starts using 99%+ of CPU every couple of
hours. `killall` on firefox or thunderbird usually fixes things (I
generally have a lot of Firefox windows open), as does switching to
another TTY and waiting, watching `top` and the HDD light as kswapd0
thrashes the disk.

While kswapd0 is using CPU, the UI starts to become unresponsive, with
interactions delayed and the mouse movemenets becoming jerky.

I've configured this machine with and without swap, with high and low
swappiness (it's currently 20, but I originally set it to 0) and nothing
affects kswapd0 using up to 100% CPU and making the entire machine
unresponsive.

In some instances it has become so bad and the disk thrashing so
consistent and long-term that only a hard power-off works to recover
control of the machine (pressing ctrl-alt-F2 for example will take in
excess of 5 minutes to respond, and the password entry in that TTY will
timeout before completing login, as will attempts to connect via SSH)

An example `free -h`
 total   used   free sharedbuffers cached
Mem:  3.8G   3.6G   157M 0B   4.3M   1.1G
-/+ buffers/cache:   2.5G   1.3G
Swap: 3.9G   719M   3.2G

I've previously used another laptop also with 4Gb of RAM, configured the
same way (except with /swap on a spinning disk rather than an SSD) and I
used that laptop with variations from 10.04 up to 12.10 with no swap
issues at all.

My desktop (Mint14), also with 4Gb of RAM  does not suffer this swapping
problem either.

General information:
3.8.0-19-generic #29-Ubuntu SM
desktop: Mate 1.6.0

[Bug 1055534] Re: [regression] since linux 3.4.0, kswapd0 uses 100% cpu when low memory is available

2013-04-25 Thread cro
I've started seeing this problem with the most recent kernel(3.8.0-19),
even when swap is turned off.

For example, when resuming from suspend, kwapd0 will start using 99-100%
if CPU according to top, even though the reported swap usage is 0.

running swapoff -a has no effect, and the only way to stop kswapd0 from
consuming all CPU is to close any process that is currently using a lot
of RAM (for example Firefox).

It is currently so bad that at times the entire computer is unusable as
kswapd0 is thrashing the disk, blocking all other IO (shell, TTY, UI)and
I am currently investigating ways to physically prevent the process from
ever starting.

[Bug 1007976] Re: Windows jump to different workspace when switching workspace

2012-06-09 Thread cro
This bug appears to relate to the place windows compiz plugin. I can
reliably reproduce this issue by enabling or disabling the plugin.

With place windows plugin ENABLED:
* rotating the cube to the right will move all maximised windows to workspace 
1, once the workspace with a maximised window on it is moved past.

With place windows plugin DISABLED
* maximised windows remain on their workspace when rotating through cube faces.

An associated bug is that when the place windows plugin is DISABLED,
new un-maximised windows are placed on the desktop with their title bars
behind the top panel. With the place windows plugin ENABLED, new un-
maximised windows are placed with their title bar below the top panel.

[Bug 764051] Re: Second monitor useless in dual desktop mode

2011-06-04 Thread cro
I think the wider issue here is that this is a specific change in
functionality, wherever it may be. Under the prior version of Ubuntu,
configuring a second monitor/second video card as a seperate X screen
would result in the second screen being set up the same as the first
when it came to window decorators. Since the upgrade, this functionality
has changed, and the X-Server is launched without a default window
manager, let alone a clone of the first monitor's window manager
setting.

Now, there is completely non-obvious behaviour happening, and for the
majority of first-time users, the fact that the second monitor *does not
work as expected* will cause consternation.

Contrary to the low improtance assertion, there are a number of valid
use-cases for configuring a second monitor with a seperate X-Server. I
use a seperate X-Server on my HDMI-out for general display work when I'm
using my laptop for other purposes. I've used it in the past for
presentation work, or for displaying server monitoring services and
displays in a way that doesn't interfere with my primary workspaces.

Not every use case for multiple monitors has them next to each other, or
even in close proximity. As I type this I have a monitor being driven by
a seperate X Server at the end of a 5 meter HDMI cable - if it was
running in Twinview then when I switched workspaces I'd lose what was
being displayed in the external monitor. And I'm not the only audience
for that second screen.

I'd heartily disagree that this is of Low importance, although I
wonder if the actual bug is in Compiz, or in the way X (or Ubuntu for
that matter) handles the user-selected configuration of multiple
X-Servers, especially where a second display is launched without a
default window manager (if one is not set for the primary display), and
where there is no obvious way to run a display manager for those without
comand line knowledge.

I struggled myself to resolve this, and I've been using Ubuntu as my
only OS (work and home) for the past 5 years or so, so I shudder to
think of the reaction of a newcomer to Ubuntu when they run into this
kind of issue.

Binary package hint: human-icon-theme

Since the Human icon theme inherits from the Tangerine icon theme
(/usr/share/icons/Human/index.theme), the package human-icon-theme
should depend on the package tangerine-icon-theme.

The Human icon theme also inherits from the gnome icon theme, so the
package should depend on the package gnome-icon-theme as well,
regardless of this dependency being provided by the package tangerine-
icon-theme. More so since human-icon-theme does not depend on tangerine-
icon-theme right now. But the inheritance from the gnome icon theme

My apologies - I didn't suggest that the problem was in the vboxdrv

installed for the previous kernel version.

It just happened that I had only one module installed for a previous
kernel version (the vboxdrv module - after I removed all the old fglrx
modules) and my contention was that it was this conflict between modules
compiled for different kernel versions that was causing the problem.
Whether it was the vboxdrv module, or some other module I don't know.
What's your dkms status output? Do you have any dkms-handled driver
modules compiled for an earlier version of the kernel? Could they be
conflicting with the new version of X?

[Bug 284505] Re: 8.543 Crashes on login screen

2008-11-03 Thread cro
Here's an update:

I managed to resolve this issue (and will cross-post to the forums as
well) by referencing this against another bug in another package/forum:
http://www.virtualbox.org/ticket/2288

I found that essentially the same X error was being caused by the
vboxdrv under Ubuntu 8.10/2.6.27-7 kernel, which seemed odd - since I
had Virtual box installed, and dkms reported that the vboxdrv module was
assigned against the earlier 2.6.24 kernel.

Disabling vboxdrv ('/etc/init.d/vboxdrv stop' followed by removing the
execute flag from the file itself) caused dkms to fail to load the
module at boot (which I had been seeing before), but 'dkms status' now
says this:

~$ dkms status
vboxdrv, 1.6.2: added 
fglrx, 8.543, 2.6.27-7-generic, x86_64: installed 

and the fglrx driver works fine.

So it may be (or at least appears to be) an issue with modules loaded
through dkms for older kernels not being disabled properly.

[Bug 284505] Re: 8.543 Crashes on login screen

2008-11-03 Thread cro
Marcus: Try removing fglrx, 8.543, 2.6.24-21-generic, x86_64: installed
(original_module exists) if you get the 'Saw signal 11' error in your
Xorg log. It appears (perhaps) to be the conflict between the module
built for the old kernel that causes the module for the new kernel to
fail.

Alejandro: As for reinstalling the vboxdrv driver - setup
(/etc/init.d/vboxdrv setup) failed for me with a compile error that's
also been seen in some versions of fglrx (although I don't have the
references to hand, something about too many parameters on one file),
which is what also led me to removing the modules compiled for previous
kernels from dkms.

It seems, from the previous couple of entries, that it is the
'installed' status of modules for previous kernels that causes the
problem. Maarcus' fails because his 2.6.24 is 'installed', but
alejandro's works because it's just 'built' not 'installed'. Of course
this also means that you can't revert to the old 2.6.24 kernel without
backing out of these module changes, and definitely points to a conflict
in the way different kernel versions of modules are handled by 2.6.27.
