The xserver crashes when enabling visual effects. To reproduce: 1. Log into GDM 2. System>Preferences>Appearance>Visual Effects>Normal Detecting driver dialog shows, "Unable to enable effects" dialog shows a slit second before returning to GDM login. Note can enable visual effects by running "compiz --replace" from the command-line. X crashes when quitting compiz in this case.

The above Ubuntu bug is being forwarded from Robert Ancell, who maintains compiz for Ubuntu. 00:00.0 Host bridge [0600]: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller [8086:2590] (rev 03) Subsystem: Dell Device [1028:0188] 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc M22 [Mobility Radeon X300] [1002:5460] Subsystem: Dell Device [1028:2003]
That compiz doesn't start in the first place is probably a compiz wrapper script failure. The crash on compiz exit should be fixed by xserver commits 2075d4bf9e53b8baef0b919da6c44771220cd4a5 and 3020b1d43e34fca08cd51f7c7c8ed51497d49ef3 .
The patches fix the problem for me, thanks.
Fixed in xserver 1.6.3.901.
