Before doing the "su"
echo $DISPLAY
If you don't have a DISPLAY set, you don't have an X enabled session
running. "Starting a terminal as an end-user" can mean a lot of things. If
you are running an SSH connection to the server from an SSH client that is
running an X session, you should have inherited an X "DISPLAY" session such
as "clientname:10".
I'm trying to be careful about calling things "X servers" because it gets
really confusing, really fast. The SSH *client* needs to be running an X
"server" in order for X applications to display locally. The argument about
which is the server and which the client for X is...... old, and confusing.
