Comment 145 for bug 728745

I can confirm the driver listed in #144 fixes the issue. I am running Gnome Shell in Ubuntu 11.10 32 bit on a Dell Latitude D820 with an NVIDIA Quadro NVS 120M video card.

Anyone attempting to install this driver must blacklist the nouveau module first. You can do this by adding the following lines to the end of /etc/modprobe.d/blacklist.conf:
blacklist nouveau
options nouveau modeset=0

and then run:
sudo update-initramfs -u

and reboot your computer.

You should then be able to run the NVIDIA driver installers listed in post #144
