Extend Displays in LXDE

[S Hartwell]

I'm running Ubuntu 12.10, and I'm new to operating other DE's. I've installed LXDE(older machine), but I can't seem to find an option for extending my displays rather then cloning them.

Does anyone have a solution? I've thought of switching into Ubuntu DE, Extending displays, then switching back to LXDE, but I'm not sure their settings carry-over.

Here is all my computer's specs. GPU is Nivida GEforce 6200 Turbocache.

What video card and how many cards are you using? Do you have "virtual" screen setting on your xorg.conf under screen section.
example "virtual 2560 2560" for two 1280x1024 monitors
