Re: Upgrade to 12.04 broke my XBMC
Looks like this thread http://ubuntuforums.org/showthread.php?t=1976109 has some useful information. There's a known bug with the nvidia 295.X drivers for older cards.
I've removed all the proprietary drivers from my new install and am using the nouveau driver instead (your system will fall back to this if you remove all the official drivers). It's still not as fast as my previous 11.10 install was, but reading the bug-thread suggests that this is fixed in 12.10 and will be fixed in 12.04 soon. Here's hoping, I miss my XBMC
