Its seems that only the "Default" script in /etc/gdm/PostSession gets processed. Is this the intended behaviour? This makes packaging harder. Or can drop-in scripts/files be enabled?
Correct - although if a file that matches the DISPLAY name exists (e.g. ':0'), that file is used instead - see:
https://help.gnome.org/admin/gdm/stable/configuration.html.en#scripting
I replace the Default file with something that just sources 'drop-in files' in a matching directory - which could be a sub-directory of /etc/gdm/PostSession/ etc
