Journalctl log of the sleep and wake cycle
SUMMARY
Screen doesn't properly stay in sleep. It will wake up by itself and stay on
indefinitely. Until user interaction, then it repeats the "sleep after x
minutes > wake indefinitely" cycle.
STEPS TO REPRODUCE
1. Set Turn Off Screen to: "1 minute" / "When locked and unlocked".
2. Screen will sleep after 1 minute.
3. After a random amount of time, the screen wakes up without user interaction.
4. Screen will sleep again after 1 minute.
5. After a random amount of time, screen wakes up without user interaction.
6. Screen will stay on forever (Only when you interact with it, it goes back to
Step 2).
OBSERVED RESULT
Screen turns off after expected time, but wakes itself.
EXPECTED RESULT
Screen stays off until user interaction.
