I'm not sure if this is actually a GNOME problem, but it seems like the most likely culprit.
Basically, I've recently installed Debian 6, and using a GNOME desktop. But I keep on getting system freezes. Basically, everything on the screen freezes, except the mouse pointer. So I can move the mouse around, but not click on anything. And the system doesn't seem to respond to anything I do with the keyboard either.
I'm honestly unsure where to start looking for the cause of the problem. Any suggestions would be welcome.
