I'm guessing you have an nvidia or ati graphics card? Both of these can 
use proprietary drivers to enable 3d acceleration (and advanced 2d 
acceleration on newer NV cards).  Easiest way to fix it would be to 
install the drivers again (System > Administration > Hardware Drivers) 
rather than a complete restore / reinstall.

It should also be possible to reconfigure X to use the appropriate FOSS 
driver if you want.  (sudo dpkg-reconfigure xserver-xorg)
