Purely speaking, X and ssh are completely separate items. Ssh will work
without X and vice versa. Ssh will also work just fine without $DISPLAY set.
On my HP-UX and RH systems, I always needed to set my $DISPLAY. You should
be looking at your Xserver more than your ssh setup.

Thanks for the reply Marshall.
As far as I can tell, at least according to what I have read, there
shouldn't be any need to set DISPLAY manually. It seems it should be
set automatically based on the setting/value for X11DisplayOffset (I
think sshd does the dirty work upon login). If this is not the case,
then I must have misunderstood.

You need to set it. Depending on your OS, you can readily script it to
automatically set it when you login. For example, in my RH servers I
put the following in /etc/bashrc:
#setup DISPLAY
XX=`who am i | sed -ne 's/.*(//;s/).*$/:0/p'` test "x$XX" != x &&
export DISPLAY="$XX"

Does anyone know why my DISPLAY variable is not getting set? I have
tried looking at the debug messages from
ssh -vv -X user@host
but I haven't seen anything suspicious. xauth is installed in the normal
location and seems to run correctly (although I'm really not familiar
with it). In my sshd_config file, the relevant options are set as:
X11Forwarding yes
X11DisplayOffset 10
#X11UseLocalHost no
#UseLogin yes
I've spent quite a bit of time googling on this problem and haven't come
up with anything yet. I suspect that it might have something to do with
installing XFree86 on Slackware 9.0 after initial OS installation (using
installpkg *.tgz on the relevant packages). I'm really at a loss for
where to turn.
Server is OpenSSH 3.5p1, OpenSSL 0.9.7a
Client is OpenSSH 4.0p1, OpenSSL 0.9.7f
Thanks in advance!
