output of lspci
After an upgrade to 2.6.34 (2.6.32 also showed that problem) from 2.6.26, 3D
stopped working.
glxinfo's output hasn't changed, however glxgears displays a black window, and
only sometimes (for example when moving it) i can see flickering gears for a
short time.
also other 3D applications are affected
i've a ati radeon mobility m6 LY and i'm using the open source "radeon" driver
it doesn't matter which AGP mode i use, or if i set it to PCI mode.
expected results: working 3d
actual results: black window, flickering gears
I'm using debian lenny and X.Org X Server 1.4.2
steps to reproduce:
start glxgears.
enjoy
