i'm trying to change the screen resolution to the sharp netwalker to be able to run a program which its maximun resolution is 640*400 in the full screen (Now it run in a window, but is really little). Can anybody help me?
did you look in the settings? There may be a Display panel. I don't have my Netwalker anymore (long story...) so can't check. If such a panel is missing, you may have to edit/create xorg.conf accordingly.
I also tried xrandr for some on-the-fly modifications (namely to create a virtual screen with panning) but it wouldn't work. If it did it would be a nice option to quickly change the resolution.
Hope this helps!
