The lightdm locking facility is an unfinished work, and lack a proper
way to lock the session, it started at the begin of the cycle, and was a
bit forgotten later in the development. It's unfortunate that it went
into the release in this state.

That's said, the less invasive way I can see to "fix" it is to
completely remove the lightdm option in lxlock. However, it will break
the "Lock" button of lxsession-logout, which need another lock system by
default to work properly by default. But, no-one is currently ready
enough out-of-the-box to work as a replacement (xscreensaver need to be
start at startup, slock provide a not-user-friedly interface, light-
locker is out of universe, and gnome-screensaver is out of the
question). So, the only way is to just remove the "Lock" button to avoid
confusion. It will be still possible to lock the session if people use
lxlock and set-up the proper configuration.

I'm preparing a patched version of lxsession with those changes, so
people will be able to test it.
