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"

But, I can connect and start Desktop/Application Sessions.
However, when I detach and resume a NX session all fonts are hidden  
and server print this error:

[II] 2012/31/07 11:59:10 NXServerUtil.set_user_keyboard() session  
connected, setting user keyboard mappings

Any idea?
