[gentoo-user] Fake Dual-Head with VNC?

[Tim Garton]

Anybody know if this is possible?  I have a single-head graphics card
capable of doing 2048x1536.  I want to start X with a virtual desktop
of 2048x768, make my ViewPort be the left half of said desktop, start
x11vnc using the "-clip" option so that it only shows the right half of
said desktop, and then use an old beater laptop to act as a view-only
VNC client that connects to the x11vnc instance.  I think it will work,
my only question is is there a way to prevent the ViewPort from moving
around in X as you move the mouse?
