<br>
I'm using 18.08.6-2 and have got X11 forwarding working using the<br>
in-built mechanism. This works fine for users who log in with 'ssh -X'<br>
and then do 'srun --x11 --pty bash'.<br>
<br>
However, I have users who start a VNC session on the login node and when<br>
they run the srun command above from an xterm within the VNC session,<br>
they get<br>
<br>
srun: error: Cannot forward to local display. Can only use X11 forwarding with network displays.<br>
<br>
Does anyone have any ideas whether this can be made to work and, if so,<br>
how?<br>
<br>
Cheers,<br>
<br>
Loris<br>
