[i945] xorg fails on i945GM (8086:27a2) (UXA bug)

[Mirko Pace]

Binary package hint: xserver-xorg-video-intel

updating to intel's driver 2:2.6.1-1ubuntu2 and libdrm-intel1 2.4.4-0ubuntu6 xorg sometimes fails to boot at all (leaving the checked red screen), sometimes ask me to switch in low-graphic mode (but Kwin work, even if a little bit slow), rarely everything go well (but Kwin still to be a little bit slow).
UXA method is active (otherwise KDE doesn't start at all).

Ask me for further files or log, I'm pretty new to xorg bug report!

Thank you for reporting this bug. The apport tool has taken care of uploading all the relevant logs and information. What I think would be very useful though is some log information together with description of what happened. In particular, when xorg fails to boot at all could you either grab the Xorg.0.log at that point if your computer is responsive enough to do that (by using a text vt with Ctrl+Alt+F1 or ssh from another computer) or if you have to restart X or restart your computer, grab Xorg.0.log.old (which is the log from the previous session). You may check the timestamp of the files (`ls -l /var/log/Xorg.0.log*`) to make sure the logs are from when you think they are.

Also, I'm not familiar with the checked red screen - can you describe it a little bit more closely?

[Mirko Pace (mirkop82)]

It's very hard to replicate issues, furthermore because after the first day of "low-graphic mode" the system never asked me more.
Anyway sometimes Kwin seems to crash (screen freeze, go black and reappear without effects and transparencies). Next time this happen I'll post the Xorg log.

But now a strange thing happens: before kdm start the screen show me the "fine red/violet checked screen" for a second. Login in Kwin work but every minute screen freeze (although mouse pointer work) and to get it working again I have to switch to a terminal (ctrl+alt+F1). Otherwise terminal is unusable: it show me the "fine red/violet checked screen".
My Xorg.o.log is in attachment. To describe the "fine red/violet checked screen" I've taken a pic, in a few minutes I'll post it.

It's not like the previous "checked screen" I mentioned but looks like.
Pic turns to blue, but is actually more "violet" than blue ;)

I had similar issue with Intel 915 GM chipset using Ubuntu 9.04 beta.
(See: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/354735)

My problem was solved after update xserver-xorg-video-intel to 2:2.6.3-0ubuntu4 to version 5.

Run Update Manager, install xserver-xorg-video-intel 2:2.6.3-0ubuntu5,
 and report if it fix the bug you reported.

 Thanks.

I notice that you are using version 2.6.1 of the driver, whereas we are shipping 2.6.3, which has a number of fixes especially for UXA. Please re-test against the Jaunty release and reopen this bug report if this is still an issue.
