Now that X11 works again without crashing and I've found a font that looks OK
I'm running into a problem again that (I think) has existed for much longer:
When I start emacs from a shell window outside the X11 session (e.g. the same
mintty that I ran startxwin in) and then iconify emacs-X11 with C-z, the cursor
won't blink and it won't respond to keyboard input after de-iconifying it from
the taskbar (I'm using the multiwindow "native" window manager). I have to
select something from the menu bar before emacs starts responding again, which
is a bit of a problem when I've switched the menu bar off... until I remember
that the context menus in the text pane are still there.
This does not happen if Emacs is started from an Xterm or the menu entry of the
X server icon in the notification area or even another mintty that's been
started from within X. Somehow that C-z makes its way to where it shouldn't go
when the controlling terminal hasn't been started from the X11 session. Ideas?
Regards,
Achim.

I can't reproduce this on my system. I'm running 64-bit Windows 7,
emacs-24.2-1, the latest Cygwin snapshot (2012-08-27), and the test
version of the X server (1.13.0-1). Here's what I tried:
1. Start mintty from the "Cygwin Terminal" shortcut.
2. $ startxwin
3. [still in the mintty window] $ DISPLAY=:0 emacs -Q&
4. In the resulting emacs window, C-z.
5. Left click on the emacs icon to de-iconify emacs.
The cursor blinks and emacs responds to keyboard input.
Are you able to reproduce your problem with 'emacs -Q'?
Ken
P.S. Shouldn't this discussion be taking place on the cygwin-xfree list?

I've tested this both with bash and tcsh, BTW since tcsh's signal handling is
apparently different from bash.

This is what doesn't work here. That is when I start the X server from another
mintty than the one that the X server is started from or when the shell is tcsh.
So if I extend your case with:
6. Start another mintty
7. DISPLAY=:0 emacs -Q&
8. In the resulting emacs window, C-z.
9. Left click on the emacs icon to de-iconify emacs.
The cursor doesn't blink and emacs doesn't respond to keyboard input.
What do you get?
> P.S. Shouldn't this discussion be taking place on the cygwin-xfree list?
I thought about it, but I suspect that signal handling is involved and hence
cygwin1.dll. Within the X server itself there seems to be no problem but maybe
I didn't try the correct sequence of events yet.

Achim.

Still no problem. I'm using only bash, not tcsh. But I gather that
you're having problems with both.
I wonder why your results are so different from mine. Do you have
something in your .startxwinrc that could be interfering? I moved my
.startxwinrc out of the way before testing.

Hmm. I'll have to try another time after a reboot with just bash alone to rule
out any interference. I have a dual core machine (no hyperthreading) if that
makes any difference.

Me too. Well, thanks for trying to reproduce anyway.

I haven't touched any .startxwinrc, the stock one just starts an xterm (which I
most of the time close right after it has opened.

Achim.

emacs hangs for me when invoking it from putty which has been
initiated by cygwin X11 which I start with startx.
But, I usually always have emacs up all the time and its not a big
pain. I would be nice for it not to freeze when being re-activated.

I'm sorry, but you didn't give enough details for me to know whether
you're reporting the same problem that Achim reported. If not, please
start a new thread. In either case, please give a precise recipe for
producing the problem. Do you have to use a non-Cygwin program (putty)
in order to produce the problem?

Sorry about that. I was more making the point that it's not a cygwin
port of emac's fault.
I also have this problem using emacs built locally from the original
gnu emacs source code. And also from the cygwin port.
C-z puts emacs off the screen, but when its re-displayed the focus
doesn't come back into the editting buffer. I have to first click on
any ol option on the top menu, and it re-activiates something that
enable editting back in the buffer.
environment: putty (also built from original source code)
This problem / hanging does not occur when emacs has been moved off
the screen by clicking on the [-] tab in the upper right side of the
emacs frame.
Can you duplicate this on your system?
C-Z # then [SHIFT][TAB] back to emacs to get it back up on the
screen. It should be frozen then. Workaround, click on [File] or
something and then escape from it and you can work in the normal
buffer.

This does sound like the same problem Achim reported (except that he
didn't mention putty). I still can't duplicate it, but I don't use
putty. Do you have the problem without putty?

I forgot to ask whether you've tried the latest Cygwin snapshot.
