thanks to all of you!
adding -listen tcp to /usr/local/etc/X11/xdm/Xservers did it, and both =
worked
:0 local /usr/local/bin/X -terminate -listen tcp :0
or
:0 local /usr/local/bin/X -terminate :0 -listen tcp
btw, LISTEN in xdm is another thing, it=E2=80=99s about listening for =
XDMCP requests.
we used it way back in the days of the VAX and Xterminals - i'm giving =
away the fact that
i=E2=80=99m an old fart :-)
thanks again,
danny
