Answer. If you get an error message including the following: Fatal error: I failed to connect to Xserver in ‘x_display_rep::x_display_rep then execute export DISPLAY=127.0.0.1:10.0 on the remote machine and make sure your /etc/hosts file is sound, i.e. it contains the line 127.0.0.1 localhost and the IP information about the local and remote machine.
