Re: [gdm-list] Document hint about 'command' in gdm.conf?

[Brian Cameron <Brian Cameron Sun COM>]

Wolfram:

You are obviously using GDM 2.20 or earlier since the latest versions
of GDM don't let you easily reconfigure the Xserver command without
recompiling GDM.  Note GDM 2.22 and later are a complete rewrite and
do not support as much configuration options as the old GDM.

I do think this is handy information.  However, I don't think it makes
much sense to update the old GDM documentation.  It probably makes
sense to add this to the latest GDM documentation if and when the
Xserver command can be more easily configured.
