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".
