Hi, I have setup slurm and enabled x11 forwarding (native).
I connect to a node from a submission node: srun --ntasks-per-node=1 --mem 100 --x11 --pty bash I am connected to the node. in debug logs, I can see that x11 setup is OK: ... [2018-10-10T09:27:48.142] [131.extern] X11 forwarding established on DISPLAY=cl1n015:92.0 [2018-10-10T09:27:48.142] [131.extern] debug: x11 forwarding local display is 92 [2018-10-10T09:27:48.142] [131.extern] debug: x11 forwarding local xauthority is .../.Xauthority [2018-10-10T09:27:48.142] [131.extern] debug: x11 forwarding - sending keepalive message ... I have a display assigned: bash-4.2$ echo $DISPLAY localhost:30.0 and Xauthority is updated: bash-4.2$ xauth list osallou/unix:11 MIT-MAGIC-COOKIE-1 .....2593f3c305e42754 slurmmaster/unix:10 MIT-MAGIC-COOKIE-1 ....b654ee70b8ccd7ad176 ==> cl1n015/unix:30 MIT-MAGIC-COOKIE-1 ...b654ee70b8ccd7ad176 But x11 fails: bash-4.2$ xterm X11 connection rejected because of wrong authentication. xterm: Xt error: Can't open display: localhost:30.0 If I ssh as root to the node with -X flag, the xterm command works as expected, so this is not a X problem itself. I do not see any error in system or slurm logs. Any idea ? I found many issues related to X11 with slurm but could not find a solution for me.
