Hi,
I have problems when I use winswitch + NX, I'm using NX programs
distributeds by x2go project
[http://www.x2go.org/doku.php/wiki:libs:nx-libs], but when I test with
desktop.devloop.org.uk server NX works normally. The problem is
described below:
First, when a start winswitch_server a notice this error:
[II] 2012/31/07 11:58:06 process_util.exec_nopipe(['/usr/bin/xset',
'q'],None,{'DISPLAY': ':0'},True,False,None,True) waiting on
process=<subprocess.Popen object at 0x18832d0>
/usr/bin/xset: unable to open display ":0"
That's the server trying to figure out if it has access to this display.
Do you own the DISPLAY at ":0" ?
Is it running from the same user-id and environment as the winswitch_server?
In any case, this should not be a problem, this is only used for
detecting existing X11 display sessions to then give you the option of
shadowing them (either via NX or VNC)
But, I can connect and start Desktop/Application Sessions.
However, when I detach and resume a NX session all fonts are hidden and
Are you saying that the fonts are there the first time (when you
initially start the application) but not the second time? (when you
re-connect)
If so, that's very odd and I've never seen that.
server print this error:

Any idea?
It's very strange that you are able to connect to the session with NX
but somehow the winswitch_server seems to fail to connect to the NX
virtual X11 server to set the keymap, etc.
Sounds like something is preventing access and generally that means
xauth issues. Do you get any SELinux denials?
What distro is this? Can you try to specify an alternate XAUTHORITY file?
Just out of curiosity, is there anything specific that prevents you from
using Xpra instead of NX?
Cheers
Antoine
