In linux setting up the dual head is not hard at all. A few simple commands will help.
First run:
$xrandr -q
to see whether there are two displays installed. Here is an example:
VGA connected 1440x900+0+0 (normal left inverted right x axis y axis) 410mm x 256mm
1440x900 59.9*+ 75.0 59.9*
1600x1024 60.2
1400x1050 60.0
1280x1024 75.0 60.0 60.0
1280x960 60.0 60.0
1360x768 59.8
1152x864 75.0 75.0 75.0 70.0 60.0
1024x768 75.1 75.0 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 75.0 72.8 72.8 75.0 66.7 60.0 59.9
720x400 70.1
LVDS connected 1280x768+0+768 (normal left inverted right x axis y axis) 264mm x 159mm
1280x768 59.9*+
1024x768 60.0
800x600 60.3
640x480 59.9
You can see two displays VGA and LVDS.
Ok let's get dual head using this:
$xrandr --output VGA --below LVDS
You can replace --below with --left-of --right-of and --above
See, dual head now!
But my video card, namely intel 915, is rather bad that it support resolution no larger than 1600x1600 so I get this error:
xrandr: screen cannot be larger than 1600x1600 (desired size 1440x1668)
or
xrandr: screen cannot be larger than 1600x1600 (desired size 2720x900)
Too bad, I need to lower the screen resolution of one screen to get it working. Any comments, thanks?

You have a good place to live in?
Arrived IA on Friday afternoon, too late to avoid the cats-and dogs rain, too late for them to give me a desk, and too late to play with the other head.
The place I is OK. Three guys (including me), toilet outside, shower room in another building.
How can I change the content of my comment after I publish it.
You can not recollect the milk you have already poured.
