Program used to detect if the lockscreen / screensaver is active on Linux, Mac, and Windows.

Requires pip install pyobjc-framework-Quartz

from lockdetect import locked
locked()

The above will either return with False, True, or a None / reason tuple.

You can also do one of the following if you're running Linux and know the exact command from the SCREENSAVERS dictionary:

from lockdetect import locked
locked('FREEDESKTOP_SCREENSAVER')

from lockdetect import locked
locked('GNOME_SCREENSAVER')

from lockdetect import locked
locked('GNOME3_SCREENSAVER')

from lockdetect import locked
locked('KDE_SCREENSAVER')
