Ubuntu 14 – vncviewer Connection Failure

Apparently, the vino-server binary included in Ubuntu release 14 requires TLS encryption, by default.

This is visible in the logs files, or if you start vino-server from the command line:

[time stamp] Advertising security type: ‘TLS’ (18)

An easy way to get around this is to set the “require-encryption” key in the Vino schema to “false”:

# gsettings set org.gnome.Vino require-encryption false
