Comment 8 for bug 522328

Federico, thanks it sounds like is improved behavior, however still not the specified behavior in the test case, so we should leave this bug report open.

That said, perhaps having the upgrader replace nvidia with -nouveau would be acceptable, in which case the test case should be updated. Refusing to do the upgrade if nvidia has been manually installed is another option I guess. The main thing is we don't want to leave the user's system broken if they've manually installed nvidia, because unfortunately this is not a rare use case.
