I have made my software switchable between GUI non-GUI by examining the DISPLAY variable - if it is NULL then x2go is not being used.
Unless, of course, you are occasionally using a local X session, or regular X forwarding, where this approach will bite you in the posterior, falsely assuming that you're running an X2Go session when it's regular X.
The deeper-rooted issue here is that X2Go-specific variables are only set when a session is run in fullscreen or windowed mode, displaying an entire desktop.
For single/published applications, no such X2Go-specific variable is set.
However, you can check if:
the command x2golistsessions is executable (=we're on an X2GoServer - important in case of NFS-mounted home directories)
AND the DISPLAY variable is set
AND client DISPLAY and SSH client IP match an X2Go session marked as "R" for running.
See <http://wiki.x2go.org/doku.php/doc:howto:ssh-agent-workaround>, section "# Part that runs in X2Go session", for an example where you could lift the required code.
What you don't need is the part that checks for a file named "~/.x2go/agent", so just remove that part.
