I've installed the new Gygwin set in my computer and I can't seem to start
any graphic interface in a remote host, for instance:
(C)SUMFO$ xclock&

(C)SUMFO$ Xlib: connection to "xx.xxx.xx.xxx:0.0" refused by server
Xlib: No protocol specified
Error: Can't open display: xx.xxx.xx.xxx:0.0
[1] + Done(1) xclock&
The DISPLAY variable is fine, I've enabled X11 forwarding (I've tried also
without enabling this option):
ForwardX11 yes
but it's still failing, I've googled for this issue with cygwin but couldn't
find anything, any help would be appreciated
I still can't tell if you are using ssh forwarding or not.
If you are using ssh forwarding, that DISPLAY setting is wrong, you should
leave it at what sshd sets it to on the remote host (typically something like
localhost:10.0)
If you aren't using ssh forwarding (not recommended), you need to use xhost
on the cygwin computer to allow access by the remote host (or equivalent actions)
I'm not sure why this would have stopped working after upgrading X (although
you don't say what version from). Perhaps you had added the X server -ac
option in the script used to start the X server, which had been updated?
