Description Daniel Walsh 2012-05-23 15:44:02 EDT
Description of problem:

Every Xephyr window comes up black, if I downgrade to f17 version everything works.  Certainly breaks sandbox badly.
Comment 1 Daniel Walsh 2012-06-18 12:01:14 EDT
 /usr/bin/Xephyr -displayfd 10
_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running

This is the cause.

Can some one look at this?  It is now in Fedora 17.
Comment 2 Daniel Walsh 2012-06-18 12:01:35 EDT
All sandbox apps are now broken.

Comment 4 Kevin Fenzi 2012-06-18 12:12:10 EDT
I am seeing this here too. :( 

This is quite anoying, as you can't use X sandbox at all with this bug.
Comment 5 Simo Sorce 2012-06-20 12:08:45 EDT
Up, can we get at least an acknowledgement from the maintainer ?

> _XSERVTransMakeAllCOTSServerListeners: server already running

this usually means you're conflicting with the existing server if $DISPLAY is :0.
/usr/bin/Xephyr -displayfd 10 :1
does that work?
Comment 7 Peter Hutterer 2012-06-21 01:09:26 EDT
sorry, ECOFFEE, didn't think of displayfd properly.

Fedora's displayfd patch printed a newline after the DISPLAY. The patch that got merged upstream doesn't, so you're not actually reading the DISPLAY until Xephyr exists.

_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running

This is a warning printed once for each display socket that was tried but didn't succeed. It has no effect otherwise and can be ignored when running with -displayfd.

Reference: xserver commit 88bacc49f06da5927f716869f5a32672a8297ed0

Got a build coming up for this.
