[Libdlo] Moving all windows back to LVDS on a laptop

[David Jablonski]

I have a laptop with an Intel i915GM processor (VGA output) and using a
DisplayLink USB->DVI (DL-125) to another monitor.  Currently have
Xinerama setup and working with both screens.  While the laptop is
connected to the external monitors I would like the laptop monitor to be
shut off.  I would then like to be able to move the desktop back to the
LVDS display (e.g. xrandr commands or the nvidia gui config) before
suspending, moving the laptop, etc.

Is this possible?  Currently I am using a kernel mode setting at boot to
turn off the LVDS permanently and only use the external monitors, but
for DR issues we need to be able to move the laptop and keep it running.

Info:
Fedora 12
