It seems to be a problem with your environment variables, or with your hostname resolution.
A couple of questions:
- Can you run a local X program in your cygwin shell? xclock for example?
- Do you set a DISPLAY variable somewhere? You should leave that to ssh, not define it yourself.
- What does 'hostname' tell you in a cygwin shell? It should not be localhost!
Hope this helps.

Do you have the following set in /etc/ssh/sshd_config | Code: | X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost yes |
They are kinda needed to forward X11 connections.
Also, you have to have your cygwin xserver started before you conenct to your remote host.
ie.
Cygwin$ startx
and then from within X you issue your ssh -X -v 192.168.0.1

I can run local xprograms in the Cygwin and I didnot set any variable myself. Hostname in Cygwin says "cuty" my Laptop name.

I have all that in the sshd_config
Anything more |

Why is your local cygwin display set to 10:0
It should be 0:0 in most circumstances.
On my cygwin box a Local xterm has the display varable set to
On my remote Gentoo box, the terminal has the display set to
I think, this is most likely the root of your issue. Get your varables right and you should be good to go.
