what causes "slogin -X" to not generate a "$DISPLAY" variable on the server?

Recently, when I do "slogin -X server" (for one particular server, not all of them) the resulting session can't run any X11 utilities (e.g. xterm) because there is no DISPLAY variable in the environment.

It used to work. I don't know what changed for sure.

Does anybody know what can cause this?

Thanks!

Rick
