Thank you Jack, Amit and José for your quick response. It works! I have edited /etc/X11/xorg.conf It now has Virtual 2304 768 as explained below by José
The command I use to enable dual head is xrandr --output LVDS --mode 1024x768 --output VGA-0 --mode 1280x1024 --left-of LVDS I'm still investigating ways to make the screen mode persistent after a reboot. It seems like I need to write a bash script. I also have sound working. I've added this line to /etc/modules snd-powermac Regards Jamie Downs 2009/5/8 José JORGE <lists.jjo...@free.fr> > A Friday 8 May 2009 03:36:23, Jamie Downs escreveu: > > I'd like to run it in dual head mode with the external monitor at > > 1200x1024. > > You must indicate in the xorg.conf that you want to use a virtual screen > bigger than your laptop's one.
