Public bug reported:
Binary package hint: compiz
I am using a Thinkpad T30 with a Radeon Mobility M7 card. I have enabled
AIGLX, but Compiz fails when run. The desktop gets squished to the upper
left quarter of the screen and most windows get drawn in white.
If I switch between these squished desktops with ctrl-alt-arrow, I get a
smooth full-screen 3D accelerated transition effect. However when I try
to open the Gnome menu, its windows wobble in very slowly, obviously
without HW acceleration. When I try to replace Compiz with Metacity
again, it just freezes. Switching to console with ctrl-alt-F1 and back
again with alt-F7 makes the screen go black and hard freezes the entire
machine.
Technical info
Compiz started with this:
compiz --indirect-rendering --strict-binding --replace gconf
Metacity was restored with this:
metacity --replace
3D acceleration is working:
glxinfo | grep direct
libGL warning: 3D driver claims to not support visual 0x4b
direct rendering: Yes
Excerpts from xorg.conf:
Section "ServerFlags"
Option "AIGLX" "on"
EndSection
Section "Extensions"
Option "Composite" "Enable"
EndSection
Excerpts from Xorg.0.log:
(**) Option "AIGLX" "on"
(**) Extension "Composite" is enabled
** Affects: compiz (Ubuntu)
Importance: Undecided
Status: Unconfirmed
