Ctrl-alt-+/- scrolls through the modes. Ctrl-Alt-+/- just beeps. My XF86Config file is included below (as configured by redhat-config-xfree86).

I attached a projector at work, and it displayed 800x600 or 640x480, even though the panel is stuck in 1024x768. Ctrl-Alt-+/- had no effect on either display. But when I got home and tried it with a spare monitor, both panel and monitor showed 1024x768. Ctrl-Alt-+/- still had no effect. > > > > > (3) Can I enable switching the external display and panel on and off > > using > > Fn-F8? > > Not sure. that is BIOS dependant as far as I know.
