[slurm-users] About x11 support

[Bas van der Vlies]

It is compile\d with `-x11` else you get an error message that the 
option is not supported.  As said it only supports RSA-keys (hardcoded 
in the src, libssh2 can handle more formats) and you must use short 
hostnames. Another thing is we had to set:
  * X11Parameters=local_xauthority

because we have autofs enabled home dirs.
