X display not working anymore
When I type xclock at the shell prompt there no xclock display
In fact any X application does not display on my screen. I have Exceed server running on my laptop from I login via ssh to my TRU64 Unix server.
All X applications use to work 7 months ago but recently they do not display anything.
Any help would appreciated.

Re: X display not working anymore
Perhaps something has changed.
"echo $DISPLAY"?

Great. Now if I knew the names of any of the
computers involved here, ...
Or were you hoping for help from some psychic
who already knows everything about your
environment?

Re: X display not working anymore
Is there a firewall between laptop and TRU64 server?
Please send more details.

So when logged in into lysithea, your $DISPLAY pointt to lysithea as outputdevice.
On the lysithea console the clock may appear and not on your laptop!
=> correct setting $DISPLAY in $HOME/.profile or $HOME/.dtprofile

Re: X display not working anymore
So on the main Lysithea console the xclock appears fine but not on my laptop.
There is a firewall between my laptop and Lysithea and I can login to Lysithea with ssh after authenticating to the firewall. We have 3 other servers running the same version of the Tru64 Unix 5.1b and all 3 servers are behind the firewall and xclock appears on my laptop for each of the 3 systems using ssh.
I have not changed any settings on ssh apart from enabelling X tunnelling in ssh for Lysithea.
I have noticed if I type xclock & on my laptop the xclock application seems to be "killed" immediately without any errors.
There are no xclock processes after I type xclock & running in the backgroundd.
I have tried using Exceed and Xming on my laptop as the X server but xclock still does not appear on my laptop. The last time xclock worked on my laptop was 8 or 9 months ago. We need to install Oracle which uses a GUI but we cannot proceed as it uses X server for the installation from a laptop.
I've looked at the sshd settings all looks fine to me.
I understand its a difficult to help me without giving you full details of the current environment.
I dont know where else to look.

Apparently you haven't. Or perhaps your
shell start-up script ("~/.profile"?) sets
DISPLAY to this value after the SSH stuff
sets it to what it should be.

Re: X display not working anymore
also try setting $DISPLAY to "hostname:0.1" instead of ":0.0"
