I'm not interested in adding a layer of "inhibitors" on top of something
that supposed to be simple. As long as I have something that exports the
whether or not SPICE is being used and/or too slow, I can implement the
necessary code in gnome-settings-daemon.
FWIW, this is the API that g-s-d uses for VNC connections, when Vino is
used:
$ gdbus introspect --session --dest org.gnome.Vino --object-path /org/gnome/vino/screens/0
<snip>
interface org.gnome.VinoScreen {
methods:
signals:
properties:
readonly s ExternalHost = '';
readonly q ExternalPort = 0;
readonly s AvahiHost = 'nuvo.local';
readonly s Host = '192.168.0.14';
readonly q Port = 5900;
readonly b Connected = false;
};
<snip>
We just look at the "Connected" value. I'm looking for something
just about as simple for Spice.
Cheers
