Bug#637300: gtk-theme setting in /etc/gdm3/greeter.gsettings doesn't work.

[Matthijs Kooijman]

Hi Sérgio,

> /etc/gdm3/greeter.gsettings comes with a gtk-theme line commented out
> but using it doesn't work and gives an error message at boot:

> Starting GNOME Display Manager: gdm3No such key `gtk-theme' in schema
> `org.gnome.desktop.background' as specified in override file

I just had a look at my /etc/gdm3/greeter.gsettings file, which
contains:

    # Theming options
    #[org.gnome.desktop.interface]
    #gtk-theme='Adwaita'

Looking at your error, does it say "org.gnome.desktop.background"
instead of "org.gnome.desktop.interface" on your system?

Or, more likely, you still have an older version of the gsettings file
[1] that still contained that [org.gnome.desktop.background] header
a few lines above the gtk-theme line and you only uncommented the
"gtk-theme=Adwaita" line, but not the "[org.gnome.desktop.interface]"
line above that.

If my suspicion is right, this bug isn't really a bug but a PEBCAK (that
might be fixed by some extra comments, though that might not be really
needed I guess).

In any case, the greeter.gsettings file itself does work: I used it to
override the background image by adding:

    [org.gnome.desktop.background]
    picture-uri='file:///etc/gdm3/thinkpad.jpg'

Gr.
