[i965] (UXA) Gdm/X freezes with gm965

[Dario Bertini]

Binary package hint: xserver-xorg-video-intel

I activated accelmethod uxa, logged out, and gdm worked fine... upon returning in a gnome session i saw improvements in compiz performance along with the absence of glitches when running 3d programs (like google-earth and the demo of world of goo) inside compiz (and also a slight decrease in glxgears fps)

then i powered off, and upon boot gdm got stuck... here's what it looks like:

no mouse pointer, no cursors, entering username/password doesn't achieve anything...

ctrl+alt+f1/f2/f3/etc. doesn't work... i was forced to powering down and rebooting in single mode to change the xorg.conf

i followed the instructions to do the freeze-test https://edge.launchpad.net/~ubuntu-x-swat/+archive/x-freeze-test/

the problem persisted with 2.6.30... i'll attach the .tgz with the logs...

then i disactivated uxa, entered a gnome session, reactivated uxa, exited the gnome session to gdm and fetched 3 other log files (i'll attach those too)

Well, next I'd like to forward this issue upstream, but first it must be retested on latest development version of Karmic to make sure the issue still happens there with the latest code. ISO images are available at http://cdimages.ubuntu.com/releases/karmic/. If you can reproduce it in the LiveCD environment, you shouldn't need to modify your installed system. Also please attach a fresh Xorg.0.log and dmesg from this testing.

i'm sorry but due to an hardware bug i'm unable to easily load a karmic live environment :/

[Bryce Harrington (bryce)]

Okay, well I suspect this bug is now fixed. There was a huge amount of work done on solving X freeze bugs in the version of -intel+kernel we now include in karmic. Feel free to reopen the bug if you can reproduce it there, once the hardware issues are sorted out.
