Now that's interesting. Perhaps I'll try that on one of my other
machines that has a problem with dri. Can I ask how you found that?

Perhaps in your case it might be time to try:

sudo dpkg-reconfigure xserver-xorg

That will take you back through many of the choices that you used during
your initial install: keyboard selection, video, framebuffer (or not) etc.

A handy package for this, and other similar technical commands is available:

sudo apt-get install configure-debian

it will then appear in the Applications|System Tools menu. *Caution* you
can screw up your system with some of the configuration choices in
configure-debian, so be sure to read up on what you are configuring. The
good thing about configure-debian, is you can just kill the terminal
session if you panic in the middle of a config.
