Hi Gabor,

(I will refer to CentOS 7, RHEL 7, Oracle Linux 7, etc as "EL 7".)

1. It appears that you can workaround the aforementioned issue with
this command:
sudo systemctl enable x2gocleansessions.service

Based on my initial research [1][2], this might not be a workaround
but instead a necessary step for installing X2Go from EPEL or from
Fedora/EL RPMs in general. I need to do more research though

2. There might be bugs in x2goserver-xsession in terms of how we
handle launching X11 sessions. The Xsession scripts provided by
Debian/Ubuntu are very different from those provided by Fedora/EL. I
do believe that Mike#1 fixed many of these bugs recently though as
part of a contract for improving our EL packages.

3. If you wish to install the X2Go Session Broker, it is not available
in EPEL. But it is available in our nightly builds for EL 7:

4. The X2Go Thin Client Environment is not available for EL.
