Public bug reported:
It appears if enabling the upstart user session (
https://wiki.ubuntu.com/RaringRingtail/ReleaseNotes#Upstart_User_Sessions_.28technology_preview.29
) there is a race between gnome-session and upstart for who starts
gnome-settings-daemon first.
Most of the time on my system, it seems like upstart wins. I'm guessing
in that case, gnome-session tries to start it, fails and gives up, which
is fine.
When gnome-session wins however, upstart continues to respawn gnome-
settings-daemon indefinitely, usually causing the wrong icon theme to
load, and causing flickering on the desktop (most noticeable in a conky
window, but affecting other windows as well).
Since it is a race, it is difficult to reproduce, but it can be forced by:
1) enable upstart user sessions
2) mkdir -p ~/.config/upstart/
3) echo manual > ~/.config/upstart/gnome-settings-daemon.override
4) Log into the ubuntu session
5) initctl start gnome-settings-daemon;
Running: initctl stop gnome-settings-daemon; will stop the endless
respawn of gnome-settings-daemon when finished testing.
My current workaround is to disable /etc/xdg/gnome-settings-
daemon.desktop from starting, and let upstart take it.
