I am a total newbie when it comes to ubuntu and linux, so anyhelp with my question would be much appreciated. I have a Acer Aspire one netbook that can run some 3d games on windows 7 but none on Ubuntu. Everytime I download one (tremulous, open arena, alien arena, ect) it goes to fullscreen and totally black. I have sound from the games but cannot see any. I thought this might be because my netbook is hooked up to a tv for a screen (since my netbooks screen is broken) and the resolution is too high, however I have no idea how to make the resolution smaller. I am only assuming this is the problem. As car as my systems hardware I have Intel® Atom™ CPU N450 @ 1.66GHz × 2 with a 32x operating system. It says my graphics are unknown, but they are intergrated. Please help!
