Hello everyone,
After fighting with x11 forwarding couple of weeks, I think i've got a few tips
that can help others.
I am using slurm 17.11.6 with builtin x11 forwarding with ubuntu server distro,
all servers in cluster share /home via
beegfs.
slurm was compiled from source.

E. make sure you can ssh -X to all servers in cluster from the loginserver
without password and you can get xeyes(for
example) to work , if this step failed, lookup up on google how to setup
sshd_config or try ssh -v for debuging
Also make shure, that the local root user will have write access to the
home directories. Some file servers like Netapp need to be configured
this way.
Otherwise the invoked xauth by slurmstepd cannot write the MAGIC cookie
into .Xauthority.
Hope, this get changed by the developers in the future.
Best,
Marco
