Fluxbox - How to Configure Dual Monitors?

Question

I have a nVidia 9800 video card and I previously setup my screen through the nVidia X Server Settings tool. But when I switch from Gnome to Fluxbox, it appears that my two monitors are treated as a single screen.

How do I configure my screens so that I can mouse between them and have separate background images, etc?

UPDATE: Here is my current xorg.conf file:

What VGA do you use? If Nvidia, nvidia has own video configuration called nvidia-settings.

One thing you can do is unhook one monitor, restart your computer, and then redetect the displays. That should get it (that's what I've had to do in the past, at least).

What about GRandR (git)?

Go in the Software Center and search for "grandr", install it and try it. Not available anymore on Ubuntu 16.04+.

Also you have ARandR, Another XRandR GUI and grandr-applet (not related).
