[Message part 1 (text/plain, inline)]

I tested on a fresh centos 6.7 installation (x2goserver) and I have not the problem. 
So i'm currently looking to my production server to find what is the key !

CentOS 6.7 is very new, is this bug also present on CentOS 6.5 or 6.6? 
Also, is SELinux active (check with the "getenforce" command)?

Is the keypad not working at all or not working properly? What are the 
symptoms? Does switching NumLock help? Are the keypresses of the 
keypad recognized by "xev" (run within the session)?

Please run x2goclient with --debug (I think that is what it is called, 
I do not have a client at hand at the moment) and send us the output. 

Also, on both connections please log the output of "xdpyinfo -ext 
XINERAMA" and "xrandr".
