So I can run this from the run box: C:\cygwin\bin\run bash -c export DISPLAY=:0.0 ; /bin/ssh vulpix xterm And I get an xterm. I have my XWin Server pinned to my start bar and so I made a shortcut with the above in it and pinned it to my start bar and the thing runs fine. Both use run. I'm thinking it's to do with Windows permissions. Does The XWin Server do a process group change or something?

Re: Cannot launch ssh from X11 system tray icon
I don't suppose anyone has any thoughts on this?
It's rendered Cygwin X11 unusable. :-(
Can any further diagnostics be enabled?

Hello Craig,
you have to use X11 Forwarding. Try
menu root {
// Comments fit here, too...
Xterm exec xterm
Xterm - Vulpix exec ssh -Y vulpix xterm -e bash --login
}
or
menu root {
// Comments fit here, too...
Xterm exec xterm
Xterm - Vulpix exec ssh -X vulpix xterm -e bash --login
}
Dirk

Hi Dirk,
I am sorry I wasn't more explicit. My ssh config file enabled X11
forwarding, as you'll note
debug1: Requesting X11 forwarding with authentication spoofing.
was in my original post.
I added -Y to the ssh and still saw both the X11 debug1 line and the symptom.
