Hello,
As far as I know there were some driver changes (correct me if I'm wrong),
that's why you now have to use xrandr to configure dual display, which is
actually really simple!
I use this line in my .xinitrc:
xrandr --output DVI-0 --left-of DVI-1 &
Added, for my needs, this specific line (Virtual 3840 1200) in the xorg.conf's
"Screen" section:
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1920x1200"
Virtual 3840 1200
EndSubSection
I attached my xorg.conf, I found this link really useful:
<http://intellinuxgraphics.org/dualhead.html>
Here is a snip from my dmesg concerning my vga adapter:
--- start ---
vga1 at pci1 dev 0 function 0 "ATI Radeon X300" rev 0x00
wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation)
wsdisplay0: screen 1-5 added (80x25, vt100 emulation)
radeondrm0 at vga1: apic 2 int 16 (irq 11)
drm0 at radeondrm0
"ATI Radeon X300 Sec" rev 0x00 at pci1 dev 0 function 1 not configured
--- end ---
Good luck!
Greetings
Didier
