Cyanogenmod 12: How to display calendar events on lock screen? Seems fairly basic, and this has been working well with CM11, but however, 
with CM12 I have not managed to configure the lock screen to show the next couple of events, without having to unlock.

I have


A Samsung Galaxy S II (Yeah, still my preferred device)
Cyanogenmod cm-12.1-20151116
The pico OpenGapps package
a PIN to unlock


I really loved the highly customizable lock screen of CM11 and it seems to be gone... Do I really need to install a lock screen app, like chronus (Is it no more packaged by default?)

Note: my question regards a different OS version than this one.
The app you are looking for is cLock. Its a widget and its still present in CyanogenMod.

Unfortunatelly, from Lollipop onwards, you can't put any widgets on your lock screen, and by that you are unable to use the described widget as you used it before.

Hovever, you can still place it on your home screen.
