Comment 95 for bug 760632

I was experiencing some lock-ups and performance issues with the previous 275.09.04 beta driver, but not nearly as bad as the nvidia-current driver currently in the natty main repository.

I have been running the new 275.09.07 driver all day without any issues thus far.

The new beta 275.09.07 is available via a ppa, with
add-apt-repository ppa:xorg-edgers/ppa

See https://wiki.ubuntu.com/XorgOnTheEdge for a script that installs and runs the test packages in a live CD/media session, for quick and easy temporary testing.

Most of you will want the nvidia-current i386 or amd64 package and perhaps the nvidia-settings package.
