Public bug reported:

I enabled "Experimental 3D support for NVIDIA cards" from Jockey, which
installed the library 'libgl1-mesa-dri-experimental'.

This does make the Nouveau driver pass the 3D support test, but Compiz segfaults when it tries to start itself. The relevant line from the terminal output seems to be:
"compiz: nv50_pc_emit.c:863: emit_flop: Controletest 'STYPE(i, 0) == 0x09' faalt."
'Controletest' is 'Control test', 'faalt' means 'fails'.

My graphics card has an Nvidia Geforce 9600GT chip. Natty is up-to-date.
