How to run a GUI application as a different user:

Suppose you are logged into your Linux box as user1 using some X window system already (with GNOME/Unity/..). Now you want to run some gui app as another user, user2.

Run:

1. xhost + - Run as the user1. This enables access to user1's X window system from other users. You should see following output: 'access control disabled, clients can connect from any host'
2. sudo su - user2 - Using your favorite terminal, log-in to second user.
3. export DISPLAY=:0.0 - optional for some apps.
