Ubuntu/GT220 Locking up over HDMI
First thing first, please forgive me if this is a duplicate post. I have been searching for days for a solution to this problem and I haven't had any success in finding a resolution.
A few weeks back I purchased an NVidia GT220 for my Ubuntu box, hoping to use it as a media/gaming box. The problem is, now that I have connected it through the HDMI cable, the graphics lock up. The one time I've been able to reproduce this consistently is when going to YouTube and clicking on any of the video links on the main page. Other times, such as while using Boxee or games, seem to occur more randomly.
I have tried uninstalling/reinstalling the NVidia proprietary drivers "latest (recommended)" several times and am pretty much out of ideas.
