Yesterday I finished building a new PC with the following:
- I5 processor
- Asus A97-A MB
- EVGA gtx 960
When I first started it yesterday I was still using Ubuntu 12.10. Most everything worked ok except there were some sound issues and the ethernet did not work. I updated to 14.02 LTS today in an attempt to fix those issues (and it did) but it messed up the graphics card drivers (or so it seemed; DOTA was running at 10 FPS.)
I ran through this set of instructions on Ubuntu Forums to try to fix the graphics card drivers. After completing them I have been stuck in a login loop. When I enter my password the screen goes black and comes right back to the log on screen.
I did ls -la .Xauthority and my user name is listed twice like it should be.
