Hi,

it may be a linux sound driver problem. I have seen this problem with 
badly supported cards. One symptom is the KDE arts sound server exiting 
right after launch, complaining about too much CPU usage. If you're 
using arts try switching it off, it may solve your problem. 
I've also had problems with an OpenGL/pygame app. The main loop ran fine 
but my fullscreen display was black, while it was supposed to show a 
bunch of moving green polys... I tracked it down and it happened to be 
an ALSA setup problem, which I solved by going to alsa-project.org and 
using the setting they advised for my card.

Hope this helps,
sylvain
