Some times we haven't access with root user directly to a server and we need execute su - to scale up to root. When we do we lose X connection but we can perform the following steps to run applications XWindow:
1.- Connect to server and list enviroment variables and xauth
Connecting to 172.1.195.38:22... Connection established. To escape to local shell, press 'Ctrl+Alt+]'.

2.- Change to root user:
johnd@JohnD-Server1:~> sudo su -
3.- Set the variable and xauth
JohnD-Server1:~ # export DISPLAY=localhost:10.0 JohnD-Server1:~ # xauth add JohnD-Server1/unix:10 MIT-MAGIC-COOKIE-1 70a56a2cb6e8d74cfefc29c1b6186efb |
Enjoy it
