<div>Hi Mahmood,</div>
<div><br>
</div>
<div>I've never tried using the native X11 of SLURM without being ssh'ed into the submit node.</div>
<div><br>
</div>
<div>Can you try ssh'ing with X11 forwarding to rocks7 (i.e. ssh -X user@rocks7) from a different machine, and then try your srun --x11 command?</div>
