Those options are no longer supported in GDM. I think that they were
removed with GDM 2.24 (at the latest, probably 2.22) and C6 is running
GDM 2.30.

You can use


in "/etc/gdm/custom.conf" to override the "-nolisten tcp" but I have
no idea about "-br -audit 4 -s 15".

"chooser=false" and "handled=true" are the default (as far as I
remember what they stand for!); no idea about "flexible=true" (I can't
remember what it stands is for!).
