Extend Desktop to another X Windows Display
I am a long time linux user of the Xinerama and other technologies for extending a desktop to multiple monitors. However when I travel with my laptop I miss the multi-monitor support I enjoy at home. Recently I acquired a second laptop for a low price. Both laptops are running Fedora 10 and 11. I use Gnome as my primary desktop environment.
I know about synergy. I use synergy all the time to control the screen of other Windows / Linux systems.
I would like to know, can I sit both my primary and secondary laptops together and achieve a Xinerama-like extended desktop environment? Ideally I would like to start a GNOME session on my primary laptop. And then start a X-Windows Desktop on my secondary laptop and extend my primary laptop's desktop onto it. I would like to be able to move Windows from the primary desktop to the secondary laptop desktop.
Would I need to use synergy to do this with some other bit of X-Windows technology? Or is there X-Windows technology that will do all this for me?
I am familiar with X Windows ability to display applications remotely. I am also familiar with Nomachine's NoX.
