Comment 8 for bug 215005

My guess. They introduced some kind of bug in jockey, which is now the
program which cares for detecting if a closed video driver is available
and needed/installable. This program does more than it looks; it not
only cares for installing the packages, but actually configures the
whole system so that they are used. Since this the fact that xorg.conf
looks much barer and, well, useless, nowadays.
Since jockey is obviously, bugged, however, this not only means that we
can't enable simply our "beloved" restricted drivers, it also means that
even if we install them, the system is not configured so to use them!
My solution was simply to open my xorg.conf file, and add the old

Driver "nvidia"

line inside the video device section. Guess what, it worked, now I am
back to compiz (note: this is kinda of a hack - which I hope is only
temporary. Would be...embarassing to launch Hardy in this situation ;-) ).

As for compiz behaving strangely today, that's another story. They are
obviously upgrading the packages in the repo, but they are doing so at a
  strange pace...only some compiz packages are currently upgraded...so
that now I have compiz-core but can't have compiz-gnome. Oh well, at
least I can have compiz enabled. Guess we'll see it fixed in some hours...

Kudos
