Cannot start compiz

[enaipi]

Binary package hint: compiz

Cannot enable Dekstop Effects. When I try to launch compiz from teminal, I get

compiz (core) - Fatal: Software rendering detected.
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0

Launching fallback window manager

I have Nvidia G210M. However, It used to work a couple of days ago.

Your nvidia driver seems to be configured incorrectly. You do not have hardware accelerated 3D rendering so compiz refuses to start.
