Comment 4 for bug 798007

One more note.
The package libgl1-mesa-glx 7.10.3-0ubuntu1 breaks:
fglrx (<= 2:8.850-0ubuntu1)
nvidia-173 (<= 173.14.30-0ubuntu2)
nvidia-current (<= 270.41.19-0ubuntu1)

However, as I said above, I use nvidia-current_275.09.07, which is the latest stable in Oneiric official repos.
Thus the installation (apt) should not even have broken anything.
