I had similar problem back on Linux Mint 7 (wich is based upon ubuntu) when I'd try update some xorg file on ~tormod update (it add some dependencies with something like ~libgl-drm~ like). Switch back with the normal xorg dependencies it did work, but update with the ~tormod update, give me back these problem.

I would like to try again the old xorg driver (without ~tormod addon) to test if this solve my problem.. but I don't know how since it was on another repository (the xorg file with ~less~ problem)
