Can you attach a copy of the output of the command lspci -vvnn as well as copies of /var/log/Xorg.0.log and /var/log/Xorg.0.log.old please? Thanks in advance.

Thanks. This is an issue with the nvidia drivers.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.

This may be the same issue as reported (against 10.10) in this bug report:

Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
