Good day.
I have noticed that on many Linux distributions with different desktop
environments, the properties
IdleSinceHint
IdleSinceHintMonotonic
are always equal to zero. This happens even if you try to use a sleep
in order to simulate a kind of user inactivity.
What is this happening?
I have written a little piece of code that is able to print on
standard output the IdleSinceHint
Thank you!
