You are in a really really unusual situation - in 15 years I've not come 
across a situation before this where a user would have GUI access to a 
system that can submit jobs directly to a cluster like you can.

I'm not sure why Slurm has this restriction but it might be that you can 
start up an xterm, change your $DISPLAY to be localhost:0 and see if you 
can start an X11 application from that.  It might be that you'll need to 
add an xauth cookie for localhost to get that going.

If it does work then (hopefully) you can use that trick to fire up jobs 
with X11 display forwarding.

All the best,
Chris
