"Can't read lock file" problem: Cygwin/X FAQ solution doesn't work for me

[Rich Signell]

Cygwin gurus,

After happily using cygwin-X for many years, I have just encountered
my first true frustration.

After updating my cygwin distribution earlier this week, I found that
I can no longer start X windows, getting the same "can't read lock
file" that other users have experienced.

I tried the solution from the Cygwin FAQ
(http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-cant-read-lock-file):

$ rm -rf /tmp; mkdir /tmp ; chmod 1777 /tmp; xinit -nolock

but this did not help. Same problem.

Here is some more info that hopefully would help, and I'd be happy to
work with someone more knowledgeable to try to diagnose and fix the
issue:

$ more /var/log/Xwin.0.log

Welcome to the XWin X Server
Vendor: The Cygwin/X Project
Release: 1.5.3.0 (10503000)

Contact: cygwin-***@cygwin.com

XWin was started with the following command line:

X :0

ddxProcessArgument - Initializing default screens
winInitializeDefaultScreens - w 1440 h 900
winInitializeDefaultScreens - Returning

Fatal server error:
Can't read lock file /tmp/.X0-lock

$ ls -sail /tmp

xinit -nolock is not the right syntax for starting the server with -nolock. As
'man xinit' says, server options follow a '--', so try 'xinit -- -nolock'

I did wonder if this is somehow related to running as a user who does not have
administrator rights. Is this true in your case?

Can you provide the output of 'strace Xwin' , please.
