"""Versioning schema somewhere between [SemVer](https://semver.org/) and [CalVer](https://calver.org/).

Schema: MAJOR.MINOR.PATCH

where:
- MAJOR is manually incremented when breaking changes are introduced
- MINOR is the release year ("25" when we are in 2025)
- PATCH is the number of the day of the year (between 1 and 365)

Hence :

(properly) Lock and turn off your screen on Pop!_OS 22.04 LTS

Pop!_OS does not turn off your screen when you lock your screen. Where you hit tue Super+L shortcut, it seems to start some screensaver which display a black image and coincidently lock your session. But the screen itself does not go to its standby mode.

Here is my solution:

1. Nuke the <Super>l shortcut occurences:
   • List conf keys: {dconf dump / ; gsettings list-recursively } | less

• Use dconf-editor to unset them
