Recently I've downloaded Steam and then TF2. I couldn't run TF2 so I tried various things to try to fix that. I didn't realize until later that I had screwed something up with OpenGL and from the research and things I've tried I believe it's the GLX that's giving me trouble. I'm not very experienced with Ubuntu yet, so I might not have my video drivers installed correctly and I still haven't figured out a solution. Any help would be appreciated. Thanks in advance.

I did solve this problem, but unfortunately I don't knit which of the things I did helped because I tried a lot of stuff but nothing worked till I rebooted. Sorry if anyone else gets this issue. It took many hours to fix.
