Answer 2

This is how I solved the problem (found in a discussion in ubuntuforum.org). I installed the old nvidia-173 driver AND downgraded xserver-xorg. After this XBMC, Unity and other GPU-hungry things started to work again.

1) /etc/apt/preferences.d/10xorg

Package: xorg xserver-xorg*
Pin: release a=oneiric
Pin-Priority: 1050
# So i can find dependencies for the older driver

2) /etc/X11/xorg.conf

# New section
Section "Extensions"
Option "Composite" "Disable"
EndSection

3) install nvidia-173 using synaptic or apt-get

Answer 3

Downgrading to 295.33 helped with my GeForce 7100. Everything works well now.

Type Ctl-Alt-F1, then:

    sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
    sudo apt-get update
    sudo apt-get install nvidia-current=295.33-0ubuntu1~precise~xup1

I found this solution in this article: Unity 3d no longer works after installing 12.04
