[Q] Cylindrical Desktop

[Pat Kane]

I have a stock Ubuntu 9.0.4 workstation that just got
a second graphics card and LCD panel, both displays
work as one large Gnome desktop.

My problem is that I want the main part of the desktop
in the center of my desk and the extended part on the
left side -- so in the "Display Preferences" I had to
interchange the position of the monitors[1][2].

Okay, that works well, except for one minor issue,
when I move the root pointer to the left on the
main screen it gets stuck at the left edge, but I
want it to go to the second display.

The best analogy that I can think of is that I want my
desktop to act like it is on the surface of a cylinder

I think this is a window manager problem, but I'm not
100% sure.  I'm willing to hack Xorg to get the  effect.

Any ideas?
