Binary package hint: xserver-xorg-video-ati
I'm starting this new report on behalf of what Bryce Harrington said here: https://bugs.edge.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/108527/comments/143
OK, first things first:
What happens?
X freezes on my Thinkpad T42 with an ATI Radeon Mobility 9600 when running Compiz.
There are no problems at all when Compiz is disabled.
This problem started with Gutsy and persists with an up-to-date version of Hardy Alpha5
Also: I have a Radeon 9600XT on my main machine which has no problems whatsoever with running Compiz on Gutsy – that's why I think this is a problem with Mobility chips.
What are the symptoms?
I can run Ubuntu with Compiz fine for some minutes. Then all of a sudden the fan kicks in and X just freezes.
What works?
Only the movement of the mouse cursor.
Restarting the system via SysRq REISUB
What does not work?
Everything else. I can't even restart X via [Ctrl]+[Alt]+[Backspace] or log into a console via [Ctrl]+[Alt]+[F1]
Infos.
I followed the steps in https://wiki.ubuntu.com/DebuggingXorg so I'm adding that output here.
X froze prior to the backtrace.
I'm also attaching Xorg.0.log, Xorg.0.log.old and the output of lspci -vvnn _right after the crash_ (recieved via ssh) as well as the xorg.conf
[Note]
For anyone else seeing freezes on ATI cards, the issue is highly hardware-specific. Unless you have the exact same hardware (see lspci output) and your backtrace shows it failing in drmCommandWrite(), please file a NEW bug. Include your Xorg.0.log's, xorg.conf, backtrace, and the output of lspci -vvnn in your new bug.

I'm adding only Xorg.0.log because Xorg.0.log.old appears to be empty.
