but what command prompt?
i have a problem with my redhat install...i used a 19 inch AOC monitor, it all worked beautifully. i used redhat for a while, then i had to take the machine back to the office. where i have a 15 inch AOC monitor. i know nothing about linux, all i know is redhat boots into a gui screen, then a terminal like type where it loads services and what nots, then a login prompt that lasts about 1/2 a second, and then my screen goes black. i know im supposed to edit some config file from a command prompt but i dont know where that command prompt is? the closest is a grub command prompt...
