[newbie] Video Modes

[Keith Taylor]

I just loaded up my first copy of Linux and am running in 640x480 with what appears to be 256 colors. Now I have looked throughout everything in KDE thats readily availiable to see if there is a place to change video modes (I like 800x600 16 bit). I read somewhere look under Settings-Desktop and Video Mode would be listed, for me it is not. Can anyone tell me where to go to alter my video mode, right now I can not see all of every window, and some buttons come up distorted.   Keith
