[Fwd: Re: Intel + GEM + suspend -> fail]

Mon Jan 5 12:51:02 PST 2009

hello,

I've investigated my issue a little more:

kernel: vanilla 2.6.28 + tuxonice + linux-phc + thinkpad-acpi
mesa, libdrm, xorg-server, xf86-video-intel git master (last built a
few days ago)

-EXA behaves fine
-UXA w/ twm is fine
-UXA w/ enlightenment wm crashes on vt switch, acpi resume and
hibernation resume

xorg.conf is the default one, but with Option "AccelMethod" "UXA".

here are the last kernel messages after vt switching

[drm] Initialized i915 1.6.0 20080730 on minor 0
