Then I rebooted in single mode => works Runlevel 3 => works Runlevel 5 => doesn't work In terms of devices, lsmod says the only differences between runlevel 3 and runlevel 5 are that both drm and radeon are loaded... If I rmmod radeon and drm while X is running suspending the devices works... I guess I don't have DRI enabled??? Just looked at the logs, I guess I don't [1]... Looking at a git log -p of gpu/drm/radeon shows lots of difference between 2.6.26 and HEAD... I see a vblank change [2] that changes the way the device is suspended, not sure if it really matters though... Alex, Jesse and/or Dave can you think of anything before I bisect? FYI my radeon is a: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500] rev 0, Cheers, Mathieu [1] (EE) RADEON(0): Static buffer allocation failed. Disabling DRI. (EE) RADEON(0): At least 21263 kB of video memory needed at this resolution and depth.
