Logs from the `journalctl --user --unit plasma-powerdevil.service -e` after
service restart
SUMMARY
Hi, when my pc screen locks after 10 mins of idle, kde powerdevil brightness
sliders are disappearing for my 2 monitors and I have to restart it through
`systemctl --user restart --unit plasma-powerdevil.service` to get the sliders
back. `ddcutil -d 1 setvcp 10 ,brightness>` is already working even when the
sliders are not there, so I'm guessing it's about the powerdevil. However I
don't see any critical/error messages on the journalctl too.
STEPS TO REPRODUCE
1. Restart the powerdevil with `systemctl --user restart --unit
plasma-powerdevil.service`.
2. Observe that all monitor brightness sliders are working fine.
3. Wait ~10 mins until screen locks and monitor sleeps (not the pc).
4. Unlock the desktop and observe that the sliders are not there anymore.
