Change resolution outside of X
Right now, I have Mandriva working fine. The only problem is that I can't get a higher screen resolution. In Windows and Knoppix I can use a resolution higher than 1024x768, but it won't let me get this high in the desktop settings in System-> Configure-> Configure your Desktop-> Display.
I can change it in System-> Configure-> Configure your Computer-> Hardware-> Change Screen Resolution, but I'm worried that X will fail to load next time if it can't find the screen because the resolution is out of bounds or something. (On this particular computer I have that trouble a lot, which is why I couldn't install Slackware on it.)
I need to be able to change the resolution from outside of X, or, startx with a parameter that will set it to some low resolution--like 640..., 800..., or 1024x768.
One page I googled claims that xrandr will do this, but it looks like that will only work INSIDE X at the command prompt.
ALso, does anyone know why does the Control Centre give me more options for the resolution than the configure desktop area?
Thanks in advance.
