Changing the XF86Config outside GUI
i've managed to set my screen resolution in the XF86Config file, however the monitor doesnt support 1152x864 at this refresh rate.
When i boot linux, i boots perfectly, however just as it logs into the GUI the screen goes blank. i press Ctrl+Alt+F3 and it switches perfectly to the command promt screen.
how can i edit the XF86Config from this command prompt?
