Package: x2goserver
Version: 4.0.1.19-3.el6
OS: Centos 6.7

Package: x2goclient
Version: 4.0.1.4-1.el6
OS: Centos 6.7

Architecture :

- Dual screen
- Gnome Desktop
- Fullscreen
- Xinerama enabled

First connection :

The first x2go connection is ok the full scrren is working as expected. (the only problem the first connection is that the keypad does not work).
To fix keypad issue, I have to logoff and start a new x2go session.

Second connection :

After the second connection the xinerama does not work anymore. For example If I maximize an application, it is present on both screens.
The worst is that the task bar is located in th middle of the screen.

I I tried to logoff and reconnect again I have the same issue.
To fix it I have to reboot the centos 6 (client side) and after the first connection is ok (but with the keypad bug).

Troubleshooting  :

- Change task bar location
- Change screen resolution
- Disable sound and print
- I also tried from last Ubuntu or fedora => same issue
- I tried to change the video card (from nvidia to an intel) => same issue


Any idea to fix this ?
Thanks in advance.
