I currently have an nvidia gtx470 with 2 x 22" 1920x1080 displays on twinview.
Since I have a spare laptop (old but works) and screen (22" 1680x1050).
A vnc server would be set up (viewonly) to the virtual screen and the laptop would login (viewonly) so its just a screen... The virtual screen would be part of my gnome session... and in theory make me a triple display setup, I've seen it done in windows... what is holding us?
Since I'm not all to experienced with vnc or xorg.conf (only just learning the settings, Can someone give me directions how to make a virtual screen/monitor and what vnc server allows for connecting to a certain screen. (realvnc does this in windows...)
I hope one of you can help Grtz, Dutchy
Edit: My Current work around is to just use unity and vnc into VMware workstation machines... alltough this kinda gets done some of the stuff I need, I would still like to have an actual third monitor
