Software

Client programs

  tigervnc              provides "vncviewer", simple BUT fast! (F8 for menu)
  vinagre               vnc, but also vnc over ssh (from GUI interface)!
  x11vnc-javaviewers    Java/Browser VNC connection applet

Export Current Display

  x11vnc       VNC server for the current X11 session ***
  x0vncserver  VNC server for the current X11 session
  x2vnc        Export display for remote control via a VNC client window.
   / rfb       the UNIX equivelent to  "rdesktop" for Microsoft Windows

  tigervnc-server      Warning system daemon start!!!
                       includes x0vncserver


Virtual VNC Display

  vncserver    Start a new internal X window server that you can run xclients
   / Xvnc      on and can be viewed and controled via a VNC client.
               But is seperate to the normal X window display.
               EG: GUI clients on remote servers without graphical console.

  tigervnc-server-minimal   Xvnc version.


Note server passwords are typically stored in
  ~/.vnc/passwd


Related to this is Remote desktop for window console access.
But this is not the same as VNC as it does not involve X windows
EG:
   rdesktop -0 -u staff\\s357751 -g 1440x900 \
            gc-prd-overlord.corp.griffith.edu.au &

Accessing a remote Display, via VNC over SSH -- looking at my laptop!

Start a VNC session on the remote machine...
  ssh -L 5901:localhost:5900  acct@remote_machine \
    x11vnc -display :0 -usepw -localhost -noipv6 -ncache 3 -ncache_cr -quiet

Note: Options can be added to a ~/.x11vncrc file instead.

OR (my convenience method)
  r -vnc h

Now access that display on your current machine
  vncviewer -geometry 1600x980 :1           # F8 for menu
  vinagre :1

Note the -ncache creates extra tall displays that will hold window cache
data (windows for moves, backgrounds behind windows, etc.
This allow x11vnc to tell VNC clients to simply copy unchanging window data,
it already has, but can make initial start up (setup cache) a bit slower.

To get x11vnc to redraw you can use ALT-L three times.
