I started with lock not working at all and partially resolved my issues by creating my own .service file (attached) in /usr/share/dbus-1/services/org.gnome.ScreenSaver.service
Before:
* Ctrl-Alt-L did not lock
* "dbus-send --print-reply --reply-timeout=100 --dest=org.gnome.ScreenSaver / org.gnome.ScreenSaver.Lock" terminated with the error:
"Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.ScreenSaver was not provided by any .service files"
* session-menu -> Lock Screen did not work
After:
* Ctrl-Alt-L works
* the dbus command works but also generates the following error:
"Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."
* session-menu -> Lock Screen still does not work
There is still another issue -- when I go to unlock by striking a key or moving the mouse, the screensaver freezes but the unlock dialog does not appear. Blindly typing my password successfully unlocks the screen.
