Description Mamoru TASAKA 2011-02-17 17:41:28 UTC 
Description of problem:
It seems that gdm (actually gnome-session) won't launch without
gnome-screensaver installed. :?-greeter.log under /var/log/gdm shows:

# cat \:5-greeter.log 
gnome-session[2566]: GLib-GIO-ERROR: Settings schema 'org.gnome.screensaver' is not installed

aborting...

I use xscreensaver (and I am the maintainer of xscreensaver on Fedora)
and I don't want to make gnome-screensaver installed.

Version-Release number of selected component (if applicable):
gnome-session-2.91.6-3.fc15.i686
gdm-2.91.6-8.fc15.i686

How reproducible:
100%

Proposal patch

So it seems that g_settings_new() is unsafe and it must be
checked beforehand if the required schema exists.

The attached patch seems to work both when gnome-screensaver is
installed and is not installed.

I no longer see this issue with newest F-15 gsettings-desktop-schemas
(testing repo enabled)
