Hello,
First post, thank you for welcoming me here. From an Ubuntu 20.04 client to an Ubuntu 20.04 server, the default repository install is working out of the box, all is nice.
But from times to times (random but around 15 min. ), with no obvious reasons, I'm losing the ability to click :

I don't know if I could run the client and/or the server with additional verbosity to try to get more hints?
On the client, you can run:
x2goclient --debug >~/x2godebug.log 2>&1
On the server, you can edit /etc/x2go/x2goserver.conf and replace
loglevel=notice
with
loglevel=debug
This will increase the verbosity of x2goserver's syslog entries.
Does that look like something familiar?
You are actually the third to encounter this issue; sadly, the other two couldn't be bothered to subscribe here to report the bug.
It seems to be a server-side issue, using Ubuntu 20.04 on the server side is the common part of the reports.
I wonder if maybe there's some kind of sleep/suspend/energy-saver at work, or maybe some kind of "scrubbing" mechanism (possibly systemd-related)?
I've seen such issues in the past, in different contexts, where cron jobs were unaware of a running X2Go session and did "stupid" things (like shutting down the server) that affected the session - because to them, it looked like there are no users logged in.
Do you think you could set up a test server with Ubuntu 20.04 that does not have a GUI, and only some very basic X applications like xterm?
Is gdm (or some other graphical login manager) running on your server? If so, could you stop it, switch the machine to text-only mode, and see if that makes a difference?
