Hi Anders,
Thank you for your prompt reply.
As a note of interest, /usr/libexec/x2go is the correct directory it seems:
[root at local ~]# LC_ALL=C ls -al /usr/libexec/x2go
total 92
drwxr-xr-x. 3 root root 4096 Jun 6 13:28 .

However, there are also files in /usr/lib64/x2go/
[root at local ~]# LC_ALL=C ls -al /usr/lib64/x2go/
total 72
drwxr-xr-x. 2 root root 4096 Jun 6 13:28 .
dr-xr-xr-x. 49 root root 36864 Jun 6 19:49 ..
-rw-r--r--. 1 root root 20852 May 19 01:02 x2godbwrapper.pm
-rw-r--r--. 1 root root 1834 May 19 01:02 x2gologlevel.pm
[root at local ~]#
I think this is where things are getting interesting.
Kindest regards,
