Comment 8 for bug 222277

I have solved the problem from Nick B.'s suggesting to a related problem in Firefox 3 in this thread.

https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.24/+bug/212648

It also references this thread which provides an updated libwfb from nvidia which resolves this issue.

To temporily fix the problem download the updated libwfb and then copy it over to your /usr/lib/xorg/modules directory, and then create a new symbolic link to libwfb.

$ wget http://people.freedesktop.org/~aplattner/wfb/Linux-x86_64/libnvidia-wfb.so.173.08
$ mv libnvidia-wfb.so.173.08 /usr/lib/xorg/modules/
$ sudo ln -sf /usr/lib/xorg/modules/libnvidia-wfb.so.173.08 /usr/lib/xorg/modules/libwfb.so

Restart xorg and everything should function normally. Enjoy!
