X: Authorization required, but no authorization protocol specified

[Markus Hoenicka <markus dot hoenicka at mhoenicka dot de>]

Hi,

I've upgraded my setup yesterday and ran into a problem running the X 
server. X ran just fine before the upgrade, just like any X client I 
threw at it. I'm aware that some defaults have changed in the couple of 
months since I upgraded, and I hope I've done everything the FAQ 
recommends to accommodate these changes. However, no joy.

Starting the X server now is noticeably slower, regardless of how I 
start it (Windows start menu, startx, or my hitherto preferred method 
startxwin). Biggest problem though is that local X clients cannot 
connect. The server output is like this:

$ startxwin /usr/bin/xterm
xauth:  file /home/markus.hoenicka/.Xauthority does not exist
xauth:  file /home/markus.hoenicka/.Xauthority does not exist
xauth:  file /home/markus.hoenicka/.Xauthority does not exist
xauth:  file /home/markus.hoenicka/.Xauthority does not exist

These messages pop up forever until I kill the server. No X client is 
started, and I can't start any other from the systray X menu either 
(this just gives additional authorization error messages).

The file ~/.Xauthority is created during startup, and it is empty after 
the server shuts down. It does not make any difference if I remove the 
empty file before restarting the X server.

.startxwinrc looks like this:

$ cat .startxwinrc
exec sleep infinity

and has these permissions:

$ ls -al .startxwinrc
-rw-rwxr--+ 1 myuser mygroup 51 Aug  6 16:34 .startxwinrc

Some enviroment variables:

$ echo $CYGWIN


$ echo $DISPLAY
:0.0

As a workaround I can start XWin manually like this:
/usr/bin/XWin :0 -multiwindow

However, I suppose the default behaviour of startx and startxwin was not 
intended to perform like this. Did I miss something obvious?

regards,
Markus
