[Q45] Kubuntu: "X server terminated unexpectedly" when playing fullscreen video after updating to KDE 4.2

[C Snover]

After installing the recent KDE 4.2 packages from intrepid-backports, I am no longer able to play fullscreen video for a significant period of time without X crashing at random. Both VLC and mplayer cause this problem. There is very little information in any of the logs about the crash.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please attach your X server configuration file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? When you do please also attach the /var/log/Xorg.0.log from this attempt. Thanks in advance.

I can’t use a blank xorg.conf in any practical manner because:
1. Bugs in the intel driver prevent my VGA monitor from having its DDC information read properly
2. Bugs in the intel driver cause a third monitor device to appear that commingles with the VGA device
3. Virtual display size needs to be set manually since the default values are too small for my monitor placement (2048×2048)
4. Bugs in the KDE monitor configuration panel do not allow monitor positioning to be set from there (this may be fixed in KDE 4.2; I have not tried it because using the configuration panel in the past has caused the hardware to get in a bad state where it sends bad signals and I have to reboot to get video output again)

“Microsoft Wheel Mouse Optical” errors are caused when the hub it’s attached to gets turned off (monitor integrated USB hub).

[C Snover (launchpad-net-zetafleet)]

This happened also when trying to play a video using mplayer-plugin in Opera. It’s becoming a major nuisance, not just because I’m losing data when X spontaneously dies, but also because a lot of the processes that were attached to the dead X server remain running and can only be removed with a kill -9.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

I've installed the Kubuntu 9.04 RC( x86) and I have the same problem: X server crashes when I try to play video in the fullscreen mode. The all players cause this problem (Kaffeine, Dragon player, Mplayer, VLC). I use default xorg.conf.
I have Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 03)

I have no found any info about this crashes In the logs.

[Alex Fomenko (falex007)]

I've enabled apport. But I don't see its logs except attached

[Alex Fomenko (falex007)]

Also I've installed xserver-xorg-core-dbg, libgl1-mesa-dri-dbg and xserver-xorg-video-intel-dbg packages

Here is X.log

[Alex Fomenko (falex007)]

The problem disapeared when I installed a new kernel 2.6.29 from this url http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.1/

[Alex Fomenko (falex007)]

also I've enabled UXA acceleration in the x.org config

part of the xorg.conf:
===========
Section "Device"
<------>Identifier<---->"Configured Video Device"
<------>Driver "intel"
<------>Option "SWcursor" "False"
<------>Option "CacheLines" "2048"
<------>Option "DRI" "True"
<------>Option "XVideo" "True"
<------>Option "AccelMethod" "uxa"
EndSection

[This is an automatic notification.]

A new major version of the -intel driver is now available in Karmic.

This version includes a major reworking of the acceleration
architecture, which resolves a huge number of issues. We do not know
whether it resolves the issue you reported.

Would you mind testing Karmic Alpha-2 and seeing if it is still a
problem? CD ISO images are available here:

  http://cdimages.ubuntu.com/releases/karmic/

If the issue can still be reproduced on karmic, please report here with
your findings, and attach a fresh Xorg.0.log from your test, and we will
be able to forward the bug upstream.

Otherwise, if the bug no longer exists in Karmic, let us know that as
well.

In the off chance you encounter different bugs while attempting to test
Karmic, please report those as new bug reports.

I'm using Kubuntu 9.10 from Alpha release, but x86_64 version. This bug didn't appear here.

Great! Glad to hear it.
