I have a problem using fullscreen mode on my Aspire One running Fedora 10. Whenever I use a fullscreen application (OpenArena or Battle for Wesnoth are the ones I use most often) it will go into windowed mode after about 7-8 minutes. It usually goes into a 1024x768 window, so the bottom of the screen is chopped off. I cannot put it back in fullscreen mode and in OpenArena it stops responding to mouse movements. Any help with this would be appreciated.
