Public bug reported:
Binary package hint: compiz
The ES1000 chipset doesn't support 3D at all. It's found on server
mobos, for example. It's not too slow with gnome and firefox, although
it (currently?) doesn't support RENDER acceleration.
Anyway, Intrepid Alpha 4 (desktop amd64 and i386) boots up to a light gray
screen with only a mouse cursor visible. This only happens after the "ubuntu"
user logs in: the gdm screen is fine. I was able to switch to a text console
and killall compiz.real, and then I could see the gnome desktop. There didn't
seem to be a window manager, but I was able to rectify that by going into
properties->appearance and turning compiz on (graying out the screen), then I
think blindly clicking effects back to none. I did switch to tty1 and kill
compiz.real again, though. So maybe it was just not killing compiz that was
the trick. Anyway, ATI ES1000 needs to be blacklisted for compiz.

Probably you should blacklist anything where glxinfo shows:
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
...
OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer
OpenGL version string: 2.1 Mesa 7.1 rc3
...
Xorg apparently sets up a software direct renderer or something, so
looking for direct rendering: Yes no longer tells you whether you have
hardware 3D.
** Affects: compiz (Ubuntu)

need to blacklist software direct rendering, e.g. ATI ES1000
