I am getting: Gtk-WARNING **: cannot open display : for remote X
 
I have another machine with Gentoo on it. I am trying to connect to it with rlogin (or ssh or whatever) from 64bit Ubuntu machine.

I get "Gtk-WARNING **: cannot open display :"

I have given xhost + on the Ubuntu machine and I
gave export DISPLAY=ip.of.ubuntu.machine:0.0 in Gentoo
yet I get the error message.

I don't think the problem is on the Gentoo box since I am able to login into this one from windows and I can do X-tunneling with PuTTy or directly use Exceed.

I assume the problem is on Ubuntu but where?

Hi, I think for security reasons, most of X clients on the penguins do not accept displays open.

Check
Code:
/etc/X11/xinit/xserverrc
and if nolisten tcp exits, comment out.

Other solution is, make ssh X11 translucent. read
Code:
/etc/ssh/ssh_config
/etc/ssh/sshd_config
In this case, you have to modify shell environment DISPLAY as accordingly.

Putty:- "Gtk-WARNING **: cannot open display :"
 
Hi,

Just you need to create a launcher. I have edited menu of KDE 3.5 to add a menu Item that pointing to /usr/bin/putty.

Just click the menu It will successfully launch putty.


Thanks for your time.
