Hi Mahmood, I've never tried using the native X11 of SLURM without being ssh'ed into the submit node.
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?

Or are you connecting via SSH? $DISPLAY >= :1 kind of means that you are physically logged into the machine I am connecting through a vnc session. Right now, I have access to the desktop of the frontend and I open a terminal and run things. I even xclock is working on the frontend and compute-0-0 (through ssh -Y). Regards, Mahmood
