Here are some examples. She is using the standard software that comes with Ubuntu.

Configure evrouter, see Mouse buttons evrouter and evrouter man pages for instructions and tips on how to find the correct device name, window name, button names etc. Example config:. Start evrouter on the client. With above configuration keyboard key XF86Back is sent to the VNC server when clicking the back button on the mouse, and XF86Forward is sent when clicking the forward button.

If needed it is possible to map the keyboard keys back to mouse button clicks on the server. In this case it might be a good idea to use keyboard keys which are never on the client or server. Install xautomation and xbindkeys on the server. This is a known issue introduced upstream. Most probably this is due to the application strictly requiring the composite Xorg extension.

For example webkit based app: midori, psi-plus, etc. Verify that the user is not logged into a physical X session, unless this option was configured with x0vncserver. Conversely, trying to log into a local X session while a VNC server service is running for that user will likely not work, and you may get stuck on a splash screen when using a desktop environment.

If copying from the remote machine to the local machine does not work, run autocutsel on the server, as mentioned in [2] :.

Warning: The default's TigerVNC security method is not secure, it lacks identity verification and will not prevent man-in-the-middle attack during the connection setup.
