--- Comment #28 from Graeme Murray <graeme.w.mur...@gmail.com> --- I have the same problem, Single monitor, hdmi port. All was working on plasma 5.26.5 on same hardware. Operating System: Fedora Linux 37 KDE Plasma Version: 5.27.0 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.1.12-200.fc37.x86_64 (64-bit) Graphics Platform: Wayland >From the journal, when I tried to change the settings I got :- org_kde_powerdevil[1766]: org.kde.powerdevil: The profile "AC" tried to activate "DimDisplay" a non-existent action. This is usually due to an installation problem, a configuration problem, or because the action is not supported followed by :- org_kde_powerdevil[1766]: org.kde.powerdevil: org.kde.powerdevil.chargethresholdhelper.getthreshold failed "Charge thresholds are not supported by the kernel for this hardware" hope this helps, -- You are receiving this mail because: You are watching all bug changes.
