How did you log into the server? Is your console on an X server? You use the term 'on my server' which makes me think you may be trying to run an X application from a text-mode console. If you used something like ssh
to login from a GUI console, then you could probably simply add the '-X
' option to the ssh
ssh -X email@example.com
This should result in a login shell where $DISPLAY is set to something like 'localhost:10', at which point you should be able to run X applications.
