My question is essentially: does Jockey not work in 12.10? In previous versions (like 12.04) after installation of the operating system this bit of software would (eventually) pop up and offer to get the correct proprietary video drivers. After I add Jockey to 12.10 it doesn't "work". I see an enormous number of postings about Nvidia and ATI drivers.
I think this howto is out of date:
There are a LOT of workarounds posted, many seem to create additional problems. Hope for some clarity in this area soon! As for me, I'm reverting to 12.04 (though I understand Debian is moving to XFCE as the standard desktop with the next release -- sounds interesting as an alternative).
