this command was suggested to me in the #ubuntu IRC channel and it worked for me:
sudo apt-get install linux-restricted-modules-$(uname -r) nvidia-glx -- [edgy] installing nvidia-glx pulls linux-restricted-modules-386 https://launchpad.net/bugs/68621 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
