I've been having a very strange problem with X11R4, xdm, and xon executed from a menu and would really appreciate any insights into this problem that anybody may have. Here is the problem: I've defined various commands to be executed from the pop-up up menus which I've set in my .twmrc (and .mwmrc) file(s). All commands work fine, except the ones which use xon. So if I try something like 'xon host xterm &' as a command from the menu, nothing happens. If I type this in an xterm, it works fine. Commands with xon which appear in my .xsession file get ignored also. However, if I source the .xsession file from an xterm, those commands work. This problem does not occur when I'm running the same setup files under R3 on an Xstation, but only occurs on displays which have xdm running on them. The problem occurs on a DECstation 2100 running R4 and an RS6000 running R3 but also using xdm. It didn't occur on the IBM 6000 until I installed xdm. It doesn't occur on a DECstation which is running DEC's R3 server and Xprompter. If anybody has any ideas, I would really appreciate hearing them. Thanks.

You are probably not setting up your environment early enough.
Commands run from window manager menus run in the environment
that was in effect when the wm started. In particular, you may
not have DISPLAY set in that environment. "xon" needs DISPLAY
set.

Thanks to all for the many helpful suggestions. It turned out that the problem was with xon itself, in that in the rsh command that it ultimately executes, it was redirecting output in an invalid way. When I was running xdm, the second exec below was beening executed, while when not running xdm, the first one below was the one to be executed. My .xsession in run under /bin/csh and is only run when using xdm. When xon was working, the SHELL was tcsh, when it wasn't, it was csh. case ${SHELL-/bin/csh} in *csh ) exec $rshell $host $rshopts -n \ exec /bin/csh -cf "\"setenv DISPLAY $DISPLAY; setenv TERM xterm;\ exec $command\" < /dev/null >& /dev/null" ;; * ) exec $rshell $host $rshopts -n \ exec /bin/csh -cf "\"setenv DISPLAY $DISPLAY; setenv TERM xterm;\ exec $command\" < /dev/null > /dev/null 2>&1" ;; esac Thanks again to all who responded.

------------------------- -------------------------
YOu may also want to use the -debug option in xon ( in the menu
entry which is probably f.exec "xon -debug ....". Start window
manager from a shell instead of login time (or kill the current
wm and restart) so as to get the out put of xon on the screen. It
should be apparent if you are missing any ENV variables.
