I like remote managing my server using ssh -X or ssh -Y and then running

I've check workstation and server X11Forwarding yes and then restarted

I've checked the logs and there's nothing about it. The error I get is:
[root@mail root]# system-config-printer
system-config-printer: could not open display
This is a graphical application and requires DISPLAY to be set.
or:
[karlp@mail ~/]$ xterm
xterm Xt error: Can't open display:
xterm: DISPLAY is not set
Of course, the obvious is to set $DISPLAY, which doesn't work either.
Well, no, it needs to be set by sshd. If you "ssh -X host.onthe.net",
when you get a shell prompt, you should be able to
$ echo $DISPLAY
localhost:10.0
Nope, it's empty...
Figgers.
in the usual case. Any problems should be evident in
/var/log/messages or /var/log/secure.
Logging in works, and the logs show that, but there's nothing about
forwarding anomalies. There is an entry about DNS lookup failed for my IP.
Should I set secure forwarding on?
I guess so. <shrug> Can't say I know what that does. I think I've
always set it.
Check also your ~/.Xauthority file on the distant server. Permissions
should be something like mine:
-rw------- 1 bob users 532 Sep 23 15:09 .Xauthority
You might try deleting it, then exit, and "ssh -X" in again. It
should mention something about creating it.
Deleted. And... not recreated on next ssh in... Hmmm?
Just thought I'd check. I was suspecting that the file had somehow
acquired bogus permissions or ownership and couldn't be written to.
Oh, I don't know why I failed to suggest this before. Turn on
verbosity with "-v", up to three times to get more details on what's
going on. When they say "verbose", they mean _verbose_. You'll have
to scroll up to see the whole mess. See if any clues come of that.
Verbose output shows debug1: Sending environment
but echo $DISPLAY still shows nothing (it shows :0.0 on localhost before
ssh)
I've seen blogs, threads and other stuff all over the net and everything
says, enable X11Forwarding. I've done this for years and have never had
that not work. Using -X or -Y should even countermand that setting if it's
off, right?
Any ideas where to go next?
