[gentoo-dev] Re: X11 Forwarding with SSH: $DISPLAY is empty!!

Hello,

I need to activate X forwarding while connecting to a remote machine via
SSH.  So, I edited the config files for ssh on this remote machine, such
as /etc/ssh/ssh_config and /etc/ssh/sshd_config, to set ForwardX11 to
yes, etc....  However, after fooling around with all these config files, I
still cannot get this remote machine to forward X, and I _think_ I know
why.  It turns out that $DISPLAY is empty (unset) on that machine.  From
what I read on other forums, $DISPLAY needs to be set on the remote
machine to enable any kind of X forwarding.

What do I do here?  After doing "ssh -X remote.host" $DISPLAY is still
unset.  If can set $DISPLAY manually, then when any app is trying to
start, it says it can't open display... blah blah blah...

I have put a similar message on gentoo-user, but none of the obvious
things have resolved this.  I think it has to do with setting $DISPLAY
rather than ssh itself - I think my config file should in principle work.
Where during Gentoo initialization is $DISPLAY set??

Thanks,
Denis

Is DISPLAY set on the machine you are connecting from? If no, thats your 
problem. If yes, try "ssh -v" for more clues.

Ok, figured it out!!  Sorry about this, people.

It turns out that "UseLogin=yes" is not compatible with X11 Forwarding!!
As soon as I set UseLogin=no in /etc/ssh/sshd_config, it works like a
charm!

Best,
Denis
