[gdm-list] Adding sessions to gdm in FreeBSD

[Bill Smith <bill rakupottery org uk>]

This is on a newly installed FreeBSD 6.2 system, with gnome2 from ports 
and kde from packages. I am trying to add kde as a session to gdm, 
according to the freebsd-gnome faq I add a kde.desktop file to 
/usr/local/etc/gdm/Sessions make it executable and restart gdm, well I 
have done this, as root, and the kde entry still does not appear in gdm.
Have I missed something silly, is there something else I need to do, 
beyond what I have written above the documentation is a bit vague.
Any definitive answers highly appreciated.
