After updating to the latest Cygwin distribution, I can no longer connect to X server. When I run startxwin (on a fresh Cygwin install), I get the following errors:

xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error

The XWin.#.log looks okay, I think (see attached).  I've set DISPLAY to :0.0.

Thanks.
