Reaching the desktop in v2.6.38-rc5 I only see the background. No Icon,widgets,windows etc. I am under the impression that everything is there - but invisible.
HW is Thinkpad T43 with Mobility Radeon X300 graphic.
Switching to the command line I see drm:radeon displaying permanently : drm:radeon_cs_ioctl error invalid command stream drm:r100_cd_track_check no buffer for AA resolve buffer
I bisected the problem to:
fff1ce4dc6113b6fdc4e3a815ca5fd229408f8ef is the first bad commit commit fff1ce4dc6113b6fdc4e3a815ca5fd229408f8ef Author: Marek Olšák <maraeo@gmail.com> Date: Mon Feb 14 01:01:10 2011 +0100
drm/radeon/kms: check AA resolve registers on r300
This is an important security fix because we allowed arbitrary values to be passed to AARESOLVE_OFFSET. This also puts the right buffer address in the register.
