my environment is Ubuntu MATE 16.04, 64bit default installation.
I activated the Synapse launcher. When I issue the suspend command from within the Synapse launcher, my notebook suspends but it does not lock the screen. So, when it resumes, it comes back to desktop without asking me to unlock the screen.
This behavior contrasts sharply to:
a) suspend via suspend hardware button (Fn-F2 on my notebook)
b) suspend via MATE menu >> Shut Down >>Suspend.
With a) and b) my notebook suspends and locks the screen. So when it resumes from a) or b) than I am asked to unlock the screen with my user password.
What could I do (perhaps preferences somewhere?) to make suspend in Synapse behave like suspend via MATE menu or via suspend hardware button, i.e. suspend and lock the screen.
Does someone have a a hint for me?
Thanks in advance,
