Hello, When my laptop starts up, the brightness is set to around 50%, which would increase to 100% when I log into KDE, change to 70% when not on AC, and drop lower when battery is critical. After the recent round of KDE upgrades, this functionality seems to have stopped working. [ebuild R ] kde-plasma/powerdevil-5.27.4.1:5::gentoo USE="handbook wireless (-brightness-control) -caps -debug" 0 KiB [ebuild R ~] app-misc/ddcutil-1.3.0:0/4::gentoo USE="X user-permissions -drm -usb-monitor" VIDEO_CARDS="-nvidia" 0 KiB Changing the brightness-control USE flag seems to go ignored by portage, it's always disabled. Installing ddcutil manually doesn't seem to help. Reproducible: Always Steps to Reproduce: 1. Install older KDE 2. Upgrade KDE Actual Results: Get stuck with a dark screen in KDE Expected Results: Working brightness controls cat /sys/class/backlight/intel_backlight/max_brightness > /sys/class/backlight/intel_backlight/brightness still seems to work.
And now all of a sudden its working, all I did was reboot again... weird.
Always restart your session after upgrades before filing bugs. brightness-control use flag is for direct control of the panel which almost no one does, it is stable-masked.
Hello, I had rebooted, twice infact. I can't explain why it wasn't working. But thanks for the reply.
