Running X on a virtual dedicated server

[Bryan O'Neal]

I tried export DISPLAY=servername:10.0 and tried to launch xlogo and all
I get is Error: Can't open Display: servername.  When I try to launch
konqueror I get cannot connect to X server servername:10.0

Thoughts?

Ok, I am trying to manually set the display using setenv DISPLAY and I
get a command not found error.  Any suggestions?

Ahhh...  Echo $DISPLAY returns nothing!

Try this command:

echo $DISPLAY

This will tell you what display the X programs are connecting to.  This
should be an SSH tunnel, something like:

:10.0

A good program to test if everything is working is "xlogo", very simple
but connects over the X11 protocol.

Also, I'd stress that "xhost +" is ONLY for debugging.  SSH should set
up the permissions so that this isn't necessary, it's a significant
security issue to leave that open regularly.
