Similar problem confirmed on Latitude C610, except that X server exits relatively cleanly and goes back to the gdm logon. The graphics adapter is a 16 MB ATI Mobility RADEON M6 LY. The above error occurred for a screen depth of 24 bits, lowering this to 16 bit causes the complete X.org shutdown. As can be seen, no error occurs within compiz or desktop-effects until the X server crashes.

The output of desktop-effects is attached.

Configuration was a custom xorg.conf on plain-vanilla 7.04, which was confirmed working well with hardware acceleration. The below xorg.conf is identical to that which worked under 7.04. The output of Xorg.0.log should also be attached.
