--- Comment #13 from Jakob Petsovits <jpe...@petsovits.com> --- (In reply to Mark from comment #12) > Can i disable KDE controlling my plugged-in monitor brightness? At the moment, only through disabling DDC/CI support by setting the `POWERDEVIL_NO_DDCUTIL=1` environment variable in PowerDevil as described in its README file: https://invent.kde.org/https://invent.kde.org/plasma/powerdevil/-/blob/master/README.md#troubleshooting--reporting-bugs The upcoming ddcutil 2.2 release will also have an option to ignore specific monitors, accessible through its config file which Plasma/PowerDevil also respects. Furthermore, on X11, Plasma will always adopt monitor brightness after a reboot, reconnection or (on Plasma 6.3) monitor sleep. As mentioned previously, forcing the configured brightness value is specific to the Wayland session. I agree an option in the Display Configuration settings is highly desirable. I didn't manage to add one for Plasma 6.3, but we should really have this for 6.4. Thanks for sharing your thoughts on what the user experience should be. In addition to the settings checkbox though, we can still work on peaceful coexistence between OSD menus and Plasma brightness settings. Plasma should read monitor brightness values at certain times to update its configured brightness value, for example before dimming or regularly in infrequent intervals. This would solve most people's issues and relegate the checkbox to only an edge case fix for buggy monitors or niche use cases. > (...) you end up having 2 places in plasma that affect brightness: > 1. KCM Display for even allowing plasma brightness control > 2. KCM power for how it's used in relation to power changes I'm currently also preparing a merge request to limit profile-based (power state) brightness settings only to internal displays, and possibly narrow down the scope further, e.g. hide and ignore the setting for systems without a battery. This should reduce unintuitive clashes between the display-specific brightness setting in Display Configuration (which mirrors the brightness applet setting) and the "Change screen brightness" setting in Power Management. All in all, there's a way forward on all of this, it takes a bit more work to make it all come together optimally. -- You are receiving this mail because: You are watching all bug changes.
