I had the same problem with a NVIDIA GeForce4 MX440 AGP 8x in Lubuntu.

I corrected all problems modifying the following line in /etc/defaults/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

adding at the end of the line:

nouveau.noaccel=1"

So the line looks like:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.noaccel=1"

After this modification you MUST run:

sudo update-grub
