Comment 22 for bug 137792

I guess that 640x480 is better than a non working X so you have to work with console which is pain for Newbies. Since displayconfig-gtk is used in rescue mode it is needed and afaik it produces a working xorg with maybe wrong resolution but this could be fixed with a text editor and irc support.
Btw. the easiest way to fix it is to don't save modesetting at least for intel cards and of course save the resolution that is recognized through displayconfig-gtk on start since dccprobe seems to produce garbage on most widescreen laptops.
