Hi,
It appears it is enough to set X11UseLocalhost=no on login node only.
Now the question is, how secure is this? :) or what is the downside?
Thanks,
Evren

Hi Evren,
I'm not sure if --pry plays a significant role here. The DISPLAY variable, by
default, is set to localhost:port_offset. SLURM itself doesn't do any x11
forwarding so when your remote application attempts to connect to the x11
server on the submission node, unless they're the same, the connection will
fail. The solution is to set X11UseLocalhost to no in your sshd_config's on
your clusters nodes, restart sshd and login again.

Hello,
I am trying to run programs with graphical output using slurm.
I tried srun's --pty option to start a shell. Everything looks fine and DISPLAY
variable is set, yet programs are not able to connect to the DISPLAY. I get
error stating failed to connect to localhost:11.0 from node1
Then I tried using P. Anderssons scripts and they seem to work fine:

So, am I understanding correctly that --pty option should allow X11 forwarding?
Is there a trick to get it working?
Thanks,
Evren
