I tried to update my i7/3770K with gtx570 to ubuntu 13.10 "saucy" today. DO NOT REPEAT MY ERROR. The main issue is that your display will just be a black screen after booting into the o/s. Video card is not recognized. You can ssh in to the machine, and the o/s is up, but boinc will not be running. The machine is essentially a brick until I can figure this out or until the geniuses that gave us this gem figure out how they screwed us.
This box was happily running both prpnet and boinc until a few hours ago.
I've poked around on the net looking for answers, finding nothing good. If anyone out there has some recommendations, feel free. I've tried all of the obvious stuff like updating drivers, multiple reboots, and so on, to no avail.
p.s. Recently lost another GPU (albeit a very slow one, but one which was previously crunching PG fine) to an o/s upgrade on a Mac. I guess I never learn.
