We've been having troubles recently using Cygwin from last week, and
today I checked my personal installation which is 3 or 4 weeks older
than that, and found the problem is present in that, too.
The symptom is that sometimes XWin.exe starts, but doesn't show an icon
in the taskbar, and you can't display any X windows (like xterm, rxvt).
They start, but no windows appear.
A look at the task list shows xrdb running.
We're not using the standard supplied startup scripts (I've attached
our simpler ones, below). We wanted to provide all these features:
1) A default working X setup. (E.g. we found -multiwindow crashed
X, but -rootless worked okay. So we wanted to change the default
options.)
2) We want easily configured per-user options.
3) We want a user to be able to start X after someone else has
started it, so we wanted to use XWin.log.$USER for the log file, not
XWin.log. (If Administrator owns /tmp/XWin.log, you have to have
admin rights to remove it, so you can start X. Or override the log
file.)
4) We want a much simpler and easy to fix script than startx. We
didn't need all the features startx provides.
I'll attach the startup script, cisraxwin.sh and the DOS equivalent,
and the default user.xinitrc.
The user can define WINDOWMANAGER in their environment to select a WM,
they can set XSERVER_ARGS in their environment to select what options
are passed to XWin, and it detects whether X was started with
-multiwindow and avoids running a WM in that case.
It all works, mostly, but maybe every 2nd time or every 4th time we
start X with it, X fails as mentioned above. Here is some sample
output, with comments typed by me in the shell, to show what's
happening.
(I've indented all the output copied from the rxvt window, to make it
clearer what is what. cisraxwin.sh, user.xinitrc and cisrastartx.bat
are attached at the end.)

Any insights would be welcome! We do also have a ~/.Xresources, though
I doubt that's relevant.

# and 0 from the bottom. The placements, incidentally, are in pixels.
#
# -fn 9x15 means choose the 9x15 (in pixels) font. And 9x15bold is just that.
#
# You can resize windows with the mouse by dragging from the top-right
