My card: 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) (thinkpad t61 integrated) When I enable uxa (Option "AccelMethod" "UXA"), I get a garbled screen. I'll attach a photo. xorg log is also attached, probably interesting lines: (WW) intel(0): libpciaccess reported 0 rom size, guessing 64kB (WW) intel(0): Register 0x61200 (PP_STATUS) changed from 0xc0000008 to 0xd0000009 (WW) intel(0): PP_STATUS before: on, ready, sequencing idle (WW) intel(0): PP_STATUS after: on, ready, sequencing on (WW) intel(0): ESR is 0x00000001 (WW) intel(0): PRB0_CTL (0x0001f001) indicates ring buffer enabled (WW) intel(0): Existing errors found in hardware state.

bugzilla doesn't like the photo (too big), here it is: http://files.hboeck.de/intel/img_3367.jpg
Could you specify which kernel/driver/xserver are you using?
You have (**) intel(0): Tiling enabled which is not supported by UXA drivers right now: http://lists.freedesktop.org/archives/xorg/2008-October/039414.html What you are required to do at the moment is change your /etc/X11/xorg.conf: Section "Device" Identifier "Configured Video Device" Option "AccelMethod" "UXA" Option "Tiling" "No" EndSection That should fix your issue.
I already got that tip on the xorg-list, with tiling disabled I get no fonts and X hangs after a short time. Log: http://files.hboeck.de/intel/xorg-log-uxa-tiling-disabled Photo of kdm: http://files.hboeck.de/intel/xorg-uxa-tiling-disabled.jpg

I have an 845G with the same problem as Hanno. Using UXA, with tiling disabled, have a display which doesn't show many display elements.
Created attachment 20279 [details] compiz on uxa With current kernel, mesa, drm and xf86-video-intel from git, situation has improved, I can start an xserver with uxa and it seems to run stable. Though when using compiz, I get a new kind of corruption (see attached image).
This bug needs to be marked as fixed since the original problem goes away. Hanno, please file a new bug for your new issue. Thanks.
