Started a new session from a Windows 7 PC with X2Go client (220.127.116.11) to a Debian Jessie PC with X2Go server (18.104.22.168-0x2go1+git20141006.949+jessie.main.1). Disconnected the session.
Tried to resume the suspended session from a Debian Jessie PC with X2Go client (22.214.171.124-1), an error message was presented that said:
Failed to restore all the required visuals.
Cant't resume the NX session on this display.
The other way around works (starting a new session on Linux and resuming it from Windows).
