Well, after a reboot of the laptop everything works perfectly! The non-password login to the backup machine was 'correct' as I had an ssh connection to that machine in another window and I use 'ControlMaster' in my ~/.ssh/config.
Why the reboot has cleared the authentication problem I don't know, I simply did a 'restart'from the panel, I didn't even power down and up again.
Could you provide us with a screenshot of your X2Go Session configuration (Session Preferences; the first tile, "Session", will be enough) on the client? Feel free to blank out user name and host IP.
I have an idea what might be the cause of your trouble ...
