Cygwin/X fatal error

Cygwin/X fatal error

[Fergus Daly]

Not quite sure what recent update has caused this failure.
Up to now (and for a very long time indeed) typing
$ /bin/xinit  /bin/xterm  --  -nolock  -multiwindow
at the mintty prompt has successfully started an xterm process.
Now I get:
"A fatal error has occurred and Cygwin/X will now exit.
Cannot establish any listening sockets."
Over the years the one-liner typed above has had to evolve with changing execs so I'm not surprised, or bothered, at this glitch.
But can anybody please advise the necessary change in syntax that will again enable a successful xterm from mintty?
Thank you!

Hi Fergus,
It works for me, so it seems not due to the sintax

Can you start X with startxwin ?

Please provide the cygcheck.out as mentioned on

SOLVED
I ran
$ rm  -vrf  /tmp/.X11*
in order to enable a "fresh start" and all is good.
On all devices and for both Cygwin32 and Cygwin64.
Thank you, Marco.

Hi all - and happy 2022 to everybody.

I have the same problem after the last update. I usually start cygwin
with Xlaunch, and
I get the same error message; now, every time I start cygwin I have to
go and delete
/tmp/.X11-unix/X0 manually. It won't be deleted when I close cygwin.
Any chance I can
do something to prevent this behavior, or shall I wait the next update
for a fix?

ciao!
