After running an upgrade ‘sudo apt-get upgrade’ and ‘sudo apt-get install xbmc’ to get my system up to date (to the latest SVN) I started getting the following error:
XBMC needs hardware accelerated OpenGL rendering.
Install an appropriate graphics driver.
Please consult XBMC Wiki for supported hardware
The first time I had this happen to me, I spent a number of hours trying to figure out how to get my system back up… but by 3 am I gave up. The next day, I reran the XBMC Live installer and got my system back up. This time, I didn’t want to have to redo all the changes I made, so I wanted to fix things. I did a bit of research and this time I tried to directly install the nvidia drivers right away before mucking around with my configuration.
