Sadly that's exactly what I'm saying. Your $DISPLAY variable is : followed
by a number and that's what I'm saying that Slurm forbids, though I'm not
clear why. The code checks like this:
I think it makes sense. Traditionally, DISPLAY=:0 means "the X server on
the machine where the client is running". You can trivally
export DISPLAY=`hostname`$DISPLAY
and Slurm will be happy, won't it? IE, you have given it an actual
network-aware DISPLAY setting.
But isn't the case being discussed where the submit host actually is
running an X server, and also on the same (trusted/routable) network
as the compute node?
In which case you don't want Slurm doing anything at all. Just let the
X client read DISPLAY from the environment propagated by Slurm.
