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

I would strongly suggest taking a look at Synergy. –  Nathan Osman Oct 17 '11 at 5:21

There is a vnc module for X that can be installed which will provide the native :0 X display when connecting remotely with the vncviewer.

  1. Install the "vnc4server" package (universe). This will provide "/usr/lib/xorg/modules/extensions/libvnc.so" (The vnc.so module for VNC 4.1.2 was changed from vnc.so to libvnc.so.)

  2. Add "vnc" to the Module section in /etc/X11/xorg.conf Section "Module" ...

    Load "vnc"

    EndSection

3.a.If your VNC server is running in a secure environment, you can disable authentication with the following configuration:

Section "Screen" ...

Option "SecurityTypes" "None"

EndSection

3.b. If your VNC server is NOT running in a secure environment, you will need to set a VNC password using the vncpasswd program:

 # vncpasswd
 Password:
 Verify:

Then tell the VNC module where the password is stored in xorg.conf:

Section "Screen" ... Option "SecurityTypes" "VncAuth" Option "UserPasswdVerifier" "VncAuth" Option "PasswordFile" "/root/.vnc/passwd" EndSection

Logout and restart X (Ctrl-Alt Backspace)

xorg.conf no longer exists. Modify the answer to up-to-date X, please. –  Oxwivi Oct 22 '11 at 9:36
    
@Oxwivi: what do you mean "no longer exists"? X can run without xorg.conf but if it is present it'll be taken into account. –  Sergey Oct 22 '11 at 11:54

@Sergey Yes it does not exist normally now, and since there's no reason for it to exist already, we answer the question assuming it's not there. Unless, of course, the OP says he already does have xorg.conf. –  Oxwivi Oct 22 '11 at 12:09
