Same problems in Intrepid 8.10 Final, on a Clevo M720R.

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

$ glxgears
1917 frames in 5.0 seconds = 383.325 FPS
1880 frames in 5.0 seconds = 375.964 FPS

$ glxinfo
(...)
direct rendering: No (LIBGL_ALWAYS_INDIRECT set)
server glx vendor string: SGI
server glx version string: 1.2
(...)

glxgears flickers and stays on top of other windows, render in Google Earth is a complete mess.

I have found something strange which could explain comments #30 and #31 :
if I switch to root :
# glxinfo gives me "direct rendering: yes" and glxgears no longer flickers.
# glxgears
2893 frames in 5.0 seconds = 578.459 FPS
2895 frames in 5.0 seconds = 578.897 FPS
and it no longer flickers.

Why this difference ?
However, Google Earth is still messed up.
