Comment 63 for bug 1532508

To a non-maintainer-but-longtime-user, it appears that the lock screen
implementation in Gnome (or whatever OS stack) is completely broken -> it
isn't secure, breaks NVIDIA drivers, inexplicably shows a different
rendition (version) of the lockscreen in some cases, and doesn't work with
popular screen savers from the Software manager.

But I suppose it all works for some people.
