I'm trying to setup the dual head on my laptop.
i'm running Xorg 7.3/Slackware12.1
I connected an old monitor at the VGA plug.
the monitor can do up to 1024x768px² in resolution.
but when i type xrandr -q i get the following:
~$ xrandr -q
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1200
VGA-0 connected 640x480+0+0 (normal left inverted right x axis y axis) 260mm x 195mm
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
S-video disconnected (normal left inverted right x axis y axis)
so it says that only the 640x480px² mode can be on.
#xrandr --output VGA-0 --mode 1024x768
xrandr: cannot find mode 1024x768
while in /etc/X11/xorg.conf I set the virtual to 2048x2048
I tried many configurations, but none of them helps.
i tried with MergedFB
then with xinerama
none of them give anything higher than 640x480 in resolution.
also, it's really hard to find any accurate information about how to setup the xorg.conf file.
