Multiple screens documentation #279

Hi, I'm unable to find any documentations/tutorials/tips on how to configure vnc server and/or client to render multiple virtual screens. Could you provide me with any tips about that?

Here are the various touch points:

  1. You can configure the initial virtual screen layout of a TurboVNC session by using the -geometry argument to vncserver. Our implementation accepts multi-screen descriptors, e.g. -geometry 1920x1200+0+0,1920x1200+1920+0.
  2. You can configure the TurboVNC Viewer to always use the server's layout by setting the desktop size option to server in the TurboVNC Viewer (either via the -desktopsize command-line option or the TurboVNC Viewer Options dialog.)
  3. You can change the screen layout within the TurboVNC session by using the xrandr command-line utility or any GUI application that understands the X11 RANDR extension.
  4. If the TurboVNC Viewer is configured to use automatic desktop resizing, which it is by default, then the viewer window will span multiple screens depending on the span mode. The default ("Automatic") is to span multiple screens only in full-screen mode, but you can change the span mode to "All monitors" (either via the -span command-line option or the TurboVNC Viewer Options dialog) in order to make the viewer window span multiple screens in windowed mode as well. When the viewer window spans multiple screens, it will automatically configure the virtual screen layout in the TurboVNC session to match the client's screen boundaries.
