Hi all,

I was having this problem also, and after some debugging I was able to trace 
the problem to a function in the file onmainwindow.cpp at the x2goclient 
package.

Enabling the debug on the client I saw at the step of creating the 
xinerama.conf file inside $HOME/.x2go/xxxxxx/ directory the following:

x2go-DEBUG-../sshmasterconnection.cpp:1469> executing remote: "sh -c 'echo 
X2GODATABEGIN:38317d7e-972d-417f-9745-ef9cb09d7e35; 
PATH=/usr/local/bin:/usr/bin:/bin export DISPLAY=:50;printf '1600 0 1600 
900\\n0 0 1600 900' >  
$HOME/.x2go/C-fpedemonte-50-1426195616_stDXFCE_dp24/xinerama.conf; echo 
X2GODATAEND:38317d7e-972d-417f-9745-ef9cb09d7e35;'"

As you can see, the "\n" is not escaped correctly. What I did was to modify the 
following line of code inside onmainwindow.cpp line 10212

        QString cmd="export DISPLAY=:"+resumingSession.display+";printf 
'"+screens.join("\\\\n")+"' >  $HOME/.x2go/C-"+
                    resumingSession.sessionId+"/xinerama.conf";

To:

        QString cmd="export DISPLAY=:"+resumingSession.display+";printf 
\""+screens.join("\\n")+"\" >  $HOME/.x2go/C-"+
                    resumingSession.sessionId+"/xinerama.conf";

After this modification, xinerama is working again.
Take note that I also replaced the single quote by double quote and escaped 
them. Without this modification the printf command was failing to create the 
xinerama.conf file.

Thanks for this excelent piece of software
