https://bugs.kde.org/show_bug.cgi?id=506706 --- Comment #6 from Steffen W. --- Found something else out. For one, the only difference between the output of kscreen-doctor -o when the brightness control is there and when it isn't is the Brightness control line. Specifically the DDC/CI line stays on "allowed" in both cases. When I enter the KDE settings application and go into display settings everything looks the same, too. Changing the display active status, the resolution or refresh rate does not lead to the brightness control for the screen (re-)appearing. However, in both cases the "Brightness" checkbox is checked. Even when no brightness control is available in the applet for the screen. In this situation, when I uncheck the Brightness checkbox the brightness control becomes available, kscreen-doctor -o reports DDC/CI "unallowed" but "Brightness control: supported, set to 100% and dimming to 100%", changing the slider does change the brightness of the screen. I'm adding a screenshot that shows this, though the UI is in German. Sidenote: It'd be a nifty feature if, during a screenshot, the UI can temporarily be changed to a different language as long as it is installed on the system. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=506706 --- Comment #5 from Steffen W. --- I currently have [steffen ~] ddcutil --version ddcutil 2.2.1 and after switching on the secondary screen mid-session the brightness control did not add a slider for the second screen, also kscreen-doctor -o still reports "Brightness control: unsupported" in this situation. -- You are receiving this mail because: You are watching all bug changes.

If it's not 2.2.1 or later, it may have already been fixed upstream; see Bug 482713. If you do have 2.2.1 or later, it's not that. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=506706 --- Comment #3 from Steffen W. --- While in a KDE session where the brightness control was recognized for the secondary screen, switching off the secondary screen and then switching it back on results in the brightness control not reappearing. Logging out of the session, then switching the screen on and then logging back in makes the brightness control appear again. -- You are receiving this mail because: You are watching all bug changes.

I just was never able to figure out why it sometimes works and sometimes doesn't - until now. -- You are receiving this mail because: You are watching all bug changes.
