Random xserver crashes after recent updates

[Andreas Hohenegger]

Since recent updates for Ubuntu 11.10 with KDE 4.8 backports PPA (yesterday) I experience random X crashes.

So far it occurred only while I was running Firefox on KDE with flashplayer plugin showing some streaming video. I have a T-series Lenovo Notebook with Intel GM965 graphics.

The backtrace from /var/log/Xorg.0.log.old is

Since the update included a new version of flashplayer I manually returned to an older flashplayer version which I was running successfully since a while furthermore I updated the Intel drivers using deb http://ppa.launchpad.net/glasen/intel-driver/ubuntu oneiric main.

I know that this is more a bug report than a question. In fact Random X crashes in Ubuntu 11.04 looks similar and has been closed.

But this bug seems to exist since a year and I would like to know whether its actually the same or if the issue is generally known/maybe considered solved.

Obviously this is a duplicate of https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/774978 . According to the numerous user comments this bug reappeared latest with Ubuntu 11.10.

[Andreas Hohenegger (hohenegger)]

I knew this report from 11.10 used the workaround of adding

Section "Module"
             Disable "record"
EndSection

to the file /usr/share/X11/xorg.conf.d/10-modules.conf .
It is still present since I upgraded. Is it not used anymore in 12.10?
