Pretty quick, thanks .. the most preferred way to install X2Go Server in Q4OS is to use specific installer from 'Software Centre'. It will add debian-baikal repos and install X2Go Server from. We instructs our customers to set 'start-q4os-x2go' as 'Custom' command in Session preferences in X2Go Client now. It works perfectly for Trinity/Q4OS.
So the new feature could be accessible for most Q4OS users after transition into the new Server's branch, when baikal lifetime cycle will finish.
What about a directory (e.g. /etc/x2go/distsessions.d) where distributions can add additional session type files. This way any distribution / desktop environment can simply add their session without having to ask anyone for inclusion in the x2go packages.

Because unlike Thinlinc for example, the user selects the session type in X2Go Client before connecting, not after connecting. This would work, but it would require the user to manually type in the session type unless it is an already listed session type in X2Go Client.
It would be very useful for letting system administrators override the session command though. Reportedly, FreeNX supports overrides via a file under /etc/.
Why not do it the freedesktop.org way finally
/usr/share/xsessions/*.desktop
?
Of course, it may come in handy to have a second location, that is X2Go specific:
/usr/share/x2gosessions/*.desktop
I've been thinking about this lately.
X2Go often must launch a different command than what the local display server must launch. The best example is that gnome flashback under X2Go needs gnome-session to be launched with --disable-acceleration-check. This applies to gnome-session 3.16 or later[1], or gnome-session 3.8 in ubuntu 14.04 with the latest update applied.[2]
At the end of the day, those files need to be shipped by
gnome-session, mate-session and the other various desktop shell
package. Thus, we need to make upstream aware of such implementations.
Once, the various desktop shell upstreams have become aware of such
files (which requires a freedesktop.org spec, see below), we will not
have to worry about the various differences anymore, because the
different upstream versions of different desktop shell (versions) will
(hopefully) always ship the correct remote session's .desktop file.
For the interim, we may be able to provide a set of extra-packages
that will provide support for those .desktop files. But the interim
phase should be kept rather short.
(I am about to write a fix for x2goserver to accommodate gnome flashback in Ubuntu 14.04. I will send a separate email about this.)
So yes, we could do this, but we need /usr/share/x2gosessions/foo.desktop to take precedence over /usr/share/xsessions/foo.desktop .
Of course.

Or more generic:
/usr/share/xsessions-remote/*.desktop

That's a valid point. We should discuss with FreeDesktop.org though.
Let's put that on the agenda for the X2Go Gathering. One of us needs
to get in contact with the freedesktop people some time earlier or
later.
