I think that Gai wants 2 different desktops or a(n?) xinerama desktop, not
to see the same desktop on both the laptop's LCD and the CRT.  I have been
waiting for this kind of support under XFree86 for my laptop's video card
for a while, as I have that functionality under Win98.  I have a Dell
Inspirion 5000e with the ATI Rage Mobility 128 video card.

To check to see if your video card indeed has 2 different "instances", type
cat /proc/pci and see if the card is listed twice.  If so, set up an
XF86Config-4 file in a dual-display configuration (check out the XFree docs
on how to do it) and use each Bus ID in a Device section.  If not, do the
same setup and use the same Bus ID in each Device section.  I have not had
any joy trying to get this to work on my laptop YET, but I keep hoping that
the ati driver will one day support this.
