Howdy, I am trying to get my cluster's native X11 support enabled, but am having some difficulty. I generated the RPMs for slurm, installed them on my systems, and added the "PrologFlags=X11" in the slurm.conf file as well. However, when I start up slurmd with the flag added, I get this error

Nicholas, Why do you have? SchedulerParameters = (null) I did not set these parameters, so I assume "(null)" means all the default values are used. John, thanks, I'll try that, and look into these SchedulerParameter more. Cheers, Colas On 2018-01-12 09:08, John DeSantis wrote: Colas,
