Description Simon McVittie 2009-07-18 03:34:55 UTC
This might be the same as Bug #22587, but the symptoms are rather different, so filing it separately. Logs etc. available from <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=537400>. When running glxgears on a Lenovo X200s (Intel GM45) with the following software, a black window is displayed; resizing the window causes fragments of the normal display to be visible momentarily. * Intel driver: 184.108.40.2062-1 (Debian unstable), also seen with yesterday's git master (commit bb30073) merged into the Debian packaging * Kernel: 2.6.31rc3 (buildserver.net snapshot) with and without i915.modeset=1, also seen with 2.6.30 (Debian unstable) without i915.modeset=1 * libdrm: 2.4.11 (Debian unstable), also seen with 2.4.11+git+20090630+de1ed01 (experimental) * Xorg: 1.6.2 (Debian unstable), also seen with prereleases Downgrading xserver-xorg-video-intel to 2.7.1 (from Debian unstable) makes glxgears work correctly (while keeping the other components the same) so this is a regression in 2.8.

Eric/Carl, can you reproduce? (Q2-rc3 is working fine on my GM45.)

*** Bug 22838 has been marked as a duplicate of this bug. ***
Comment 3 Simon McVittie 2009-07-21 04:37:11 UTC
Upgrading to Mesa 7.5 fixed this for me; perhaps the new Intel driver tickles a recently-fixed Mesa bug or something?
Comment 4 Eric Anholt 2009-07-21 11:38:19 UTC
Works for me with mesa 7.4, 7.5, or master, but I'm on server master. Are you still concerned with following up on this?

Simon, what's the previous mesa version used in your original report? I guess this bug could be closed. Leonid, if upgrading to mesa-7.5 doesn't fix it for you, you could reopen your bug.
Comment 7 Simon McVittie 2009-07-22 04:54:13 UTC
I was previously using Mesa 7.4.4 from Debian unstable.
