Are you talking > about the indicator *on the lock screen* showing the brightness of the > screens when you change it? (As opposed to Brightness and Color in the > system tray) I'm talking about Brightness and Color in the system tray Looking at $journalctl --user -xeu plasma-powerdevil.service the issue seems to be related to this: org.kde.powerdevil: [DDCutilDetector]: Failed to initialize callback After reinitialize plasma-powerdevil.service I can adjust brightness again, but after a idle lockcreen I can see the same behavior again -- You are receiving this mail because: You are watching all bug changes.
