No idea if I replied this to this particular thread already (if I have
sorry for the duplicate).
I had issues getting X forwarding to work with SLURM at the start.
Worked via SSH; no authentication / xauth problems when doing via SLURM.
Turned out to be caused by the nodes having their hostname set to their
'long' hostname (i.e. including domain) - I think that might be Red Hat
default? I 'fixed' it by changing things so all things cluster (i.e. all
things that have SLURM installed) have their hostname set to the short
hostname.

I believe that was the case, we compiled it with x11 support, however,
further debugging suggests that there's an issue writing to the

If you're getting an .Xauthority error, then X11 support was definitely
compiled into Slurm. The most common cause of .Xauthority issues is the
user's home directory hitting their quota limit. Could that be the case
here?
