Re: [X2Go-User] x2go local desktop connection on rpi

  I have found this not only happens with x2go but also with nx and vnc

and I believe it has to do with systemd sessions.

 This is I think an issue with Ubuntu, it won't allow two graphical

logins from same user on same machine, but if you originate with a different UID than you connect with it is okay.

The relevant information is probably in the server side session log (/tmp/.x2go-<username>/C-<username>-<displaynum>.*/session.log. You should find the reason why the connect did fail.

I would also suggest switching to nx 3.5.99.13 which offers the tolerancechecks (see man nxagent) option to make reconnects possible where 3.5.0 simply does not allow them. Here's how: https://wiki.x2go.org/doku.php/doc:howto:nx-libs-betatesting

You'd have to suspend your session, then edit /tmp/.x2go-<username>/C-<username>../options (add the tolerancechecks=<yourvalue> option), then try to reconnect.
