So I finally found enough time at $work to set up my triple monitor desktop. I received an new desktop and monitor a few months ago; I was already running dual monitors and the new system came with a monitor.
I am running Fedora16 on my desktop with Xfce desktop environment. The new system is a Dell Optiplex 980 with an ATI Radeon 3450HD. I added the ATI Radeon X600 (PCIE) card out of the old system, a Dell Optiplex GX620. Both cards have the capability to run dual monitors so I currently have the capability to run four screens. Configuration is posted below the fold.
