I only noticed this in the last week or so, and assumed I'd messed up
something with Windows 10 permission, which is still a possibility. My
first attempt to "fix" this was to reinstall pretty much everything in
Cygwin that was part of X11 or Base. And that seemed to fix
things...until I rebooted Windows.
There are no errors in the logs, not stackdumps, nothign to indicate
anything is not working. The X log is below. You'll notice it says
"executing '/bin/mintty', pid 3152"
but that window never opens. If I start a shell directly via my desktop
shortcut, which has this as it's target
C:\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico -
I can see that there is no PID 3152.
My .XWinrc is this:
---- .XWinrc ----
menu root {
"Cygwin Terminal" exec "/bin/mintty -e /bin/bash"
Emacs exec "/bin/emacs"
xterm exec "/bin/xterm"
notepad exec notepad

RootMenu root

and my .startxwinrc is
---- .startxwinrc ----
if [ -f $HOME/.Xdefaults ]; then
xrdb -merge $HOME/.Xdefaults &
fi
sleep infinity
----
I'm lost on what might be causing this. One thing that I *did* change,
though that was over a month ago, was to add the Cygwin sshd service. On
the off-chance that that was the issue, I disabled it and rebooted to
get a clean start. No joy, I still can't launch from the .XWinrc menu.
The log entry makes it clear that it is seen and is trying.
Oh, and from a mintty shell, if I set DISPLAY=:0.0 when X is running, I
*can* launch other X apps.
