Title:
lightdm should not have a pulseaudio config
Status in lightdm package in Ubuntu:
Confirmed
Bug description:
If the directory /var/lib/lightdm/.config/pulse exists, then whenever
the screen goes blank, the sound volume changes, mutes, or takes on
some other random parameters specified by this file. It does not reset
on unlocking the screen. This is an extraordinarily dumb behaviour
which can be temporarily remedied by deleting that directory, or
swapping out lightdm for xscreensaver.
Please make sure that lightdm cannot write a pulse config file, or
that consolekit or whatever for pulseaudio does not use system users
as sources for parameters, and so forth.
