There is a slight difference between unity-settings-daemon and gnome-
settings-daemon code paths.
Specifically:
msd = '/usr/bin/mate-settings-daemon'
usd = '/usr/lib/unity-settings-daemon/unity-settings-daemon'
gsd = '/usr/lib/gnome-settings-daemon/gnome-settings-daemon'
if osextras.find_on_path(msd):
extras.append(subprocess.Popen(
[msd], stdin=null, stdout=logfile, stderr=logfile,
preexec_fn=self.drop_privileges))
elif (osextras.find_on_path(usd)):
# Wait until xsettings plugin is activated
xsettings = SignalWatcher(self, usd,
"org.gnome.SettingsDaemon",
"/org/gnome/SettingsDaemon",
"PluginActivated",
"xsettings")
# the SignalWatcher will run until the signal is seen...
extras.extend(xsettings.run())
# At this point we're sure the usd xsettings plugin is
# available, we can continue setting up the session.
elif osextras.find_on_path(gsd):
extras.append(subprocess.Popen(
[gsd], stdin=null, stdout=logfile, stderr=logfile,
preexec_fn=self.drop_privileges))
Thus in u-s-d case there is an extra blocking wait on u-s-d to initialise
xsettings before proceeding.
I do not know if something similar is required in g-s-d case, to e.g.
wait for g-s-d to be fully up.
However, longer term, imho ubiquity-dm should not at all be in use at
all, and instead we should boot to gdm3 normally and have e.g. a casper
override to start up in ubiquity installer mode, rather than full
session.
