Hi Everyone.
Following a Windows 10 version 1909 update Cygwin/X fails to start. It ends
with:
(--) 16 mouse buttons found
(--) Setting autorepeat to delay=500, rate=31
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error
[1]+ Exit 1 startx -- :1 -multiwindow -clipboard
If I run XWin under gdb with xorg-server-debuginfo package installed I can see
this stack trace:
Thread 1 "XWin" received signal ?, Unknown signal.

Backtrace stopped: previous frame inner to this frame (corrupt stack?)

The ICA reference reflects my Citrix connection to a virtual Windows 10
desktop. I am working in a corporate setting however I do have admin rights to
this virtual machine. Based on "connection refused" my hypothesis was our
Windows 1909 push may have blocked ports Xwin is using. If there are specific
Windows Defender Firewall rules that are required I would be happy to put them
in. The bit of firewall setup I've tried thus far has not helped. This
backtrace though makes me think this may be a keyboard configuration issue.
Any advice and guidance on how to debug this problem will be greatly
appreciated. Several on our development team rely on Cygwin/X and are rather
unhappy to now be restricted to command line tools until we can get this
resolved.
Kind regards,
-Randy Galbraith
