Oops. Never install nvidia .run files in debian, ever. You fuck up all the
gl redirection libs this way. Only install nvidia drivers from debian
repo (self compile using apt-src from experimental if you really need the
latest ones). You now need to uninstall using nvidia installer, force
reinstall all the gl related stuff (mesa, etc), than install nvidia drivers
from repo.
