Re: Ubuntu video driver error
the problem is, that you don't even tell us your problem!
First of all, go back to the ubuntu websites and start reading their documentation. There is certainly a howto describing what you have to do to get nvida&compiz running. If you still have problems after that, tell us exactly what kind of problems. Also as root (or with that sudo crap) run nvidia-bug-report.sh. Just open a shell like konsole and run it. Post the output here.
