I know something like this has been posted before, but I read through it and it didn't quite make sense. I'm running Ubuntu 12.04 32bit and an unknown graphics card system (as it says on my system details), and I'm new to Ubuntu/Linux. I've run SL before on this particular computer, but on windows xp, and it ran fine. So there shouldn't be an issue with my graphics card. Anyway, when I try to run SL it only asks how if I want run through the terminal, look at through text form, or just run. When I go through the terminal it does some things and and the window just shuts off. When I just run it nothing happens.
