[slurm-users] About x11 support

Is there any way to query slurm to see if the x11 module has been compiled?
Currently, I am using the slurm roll on rocks 7. Previously, I was able to
use spank with slurm roll 17.

While, the spank rpm is now uninstalled, I tried the following cases:

1)
[mahmood at rocks7 ~]$ srun --nodelist=rocks7 -n 1 -c 6 --mem=8G -A y8 -p RUBY
xclock
Warning: Missing charsets in String to FontSet conversion
which shows the xclock

2)
[mahmood at rocks7 ~]$ srun --x11 --nodelist=rocks7 -n 1 -c 6 --mem=8G -A y8
-p RUBY xclock
srun: error: Cannot forward to local display. Can only use X11 forwarding
with network displays.


3)
[mahmood at rocks7 ~]$ srun --nodelist=compute-0-5 -n 1 -c 6 --mem=8G -A y8 -p
RUBY xclock
Error: Can't open display: :1
srun: error: compute-0-5: task 0: Exited with exit code 1


4)
[mahmood at rocks7 ~]$ srun --x11 --nodelist=compute-0-5 -n 1 -c 6 --mem=8G -A
y8 -p RUBY xclock
srun: error: Cannot forward to local display. Can only use X11 forwarding
with network displays.
