[slurm-users] x11 forwarding not available?

[Dave Botsch]

Ok. Progress.

Per:

https://bugs.schedmd.com/show_bug.cgi?id=4721

I was missing PrologFlags=x11 in slurm.conf .

So now my issue is just that X11 forwarding doesn't work... slurmd.log:

[2018-10-16T11:38:34.136] [27.extern] error: ssh public key

Will have to try RSA again and see if that gets things going.
