It does not make any difference about the session suspension issue if I
either set "-options" alone (without the +=) or with any combination of
the other occurences in the file /etc/x2go/x2goagent.options

The problem that I get when adding the/setting the -option switch is
that I cannot suspend the session any more (e.g. the
x2gosuspend-session command does not suspend the session) and I'm
getting the following line every 2 seconds in the log:

/usr/sbin/x2gocleansessions[1115]: <user>-50-1542963751_stDXFCE_dp32:
state file for this session does not
exist: /tmp/.x2go-<user>/C-<user>-50-1542963751_stDXFCE_dp32/state
(this can be ignored during session startups)

I also have some files missing as I stated previously (clients,
keyboard, state) which I think is linked somehow to the issue.

Do you mean I should wrap a script around the x2gostartagent executable?
Or is there an configuration file somewhere that I can use?

I have only 2 lines uncommented on this file, and I checked several
times, so I don't think there is any syntax error.

We are using the X2Go client, I will try to grab the debug version and
run it.

Thanks for the suggestion. I barely have time to debug the issue, I'm
afraid having to patch and compile anything will be too time consuming.
I guess I'll wait for nightly builds if the patch is considered for
inclusion in the project.
