This is not an error, Mahmood could fix. This is the same for me. It is,
because I can submit from my workstation directly to SLURM. So DISPLAY
ist set to ":0".
So it is a socket, which is prohibited by SLURM:
if (display[0] == ':') {
error("Cannot forward to local display. "
"Can only use X11 forwarding with network displays.");
exit(-1);
}
The 'fix' for Mahmood would be to ssh to another host and then submit
the X11 job.
Best
Marcus
