We see "kill task failed" issues but as Marcus says that's not related 
to X11 support, when we see it it's usually because the kernel cannot 
evict dirty pages from cgroups quickly enough (or at all) for Slurm's 
liking.  You may want to tweak the default timeout for your 
UnkillableStepTimeout from the default of 60 seconds.

All the best,
