Bug ID: 499519 Summary: Powerdevil brightness slider disappears after screen locks and monitor sleeps Classification: Plasma Product: plasmashell Version: 6.2.4 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: Brightness and Color widget Assignee: plasma-b...@kde.org Reporter: brkcnkh...@gmail.com CC: natalie_clar...@yahoo.de Target Milestone: 1.0 Created attachment 177971 --> https://bugs.kde.org/attachment.cgi?id=177971&action=edit 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.
