Hello! KDE plasma wayland session on fedora 37 here. I noticed that the brightness (even if the indicator always shows 100%) is “less bright” with the charger unplugged, and brighter with the charger plugged in.
the strange thing is that this does not happen instantly, when I unplug it it slowly lowers the brightness, almost imperceptibly, and in about 4~5 seconds it stops at a lower brightness. the same happens when I plug it back.
am I the only one with this problem? googling it returned only unrelated issues.

(note, in settings > energy saving the option to change screen brightness on battery power is unchecked)

thanks in advance!

    Did you check the Energy Saving settings? There should be a setting to set the screen brightness dependent on whether the device is plugged in/running on battery.

      OP said

      So either that setting is ignored or there’s two competing energy saving modules active or there’s a but in the setting or something completely else…

      thanks for the answer!

      What computer model is that? Might be a special feature of your firmware.

      it’s a Dell Vostro 15 3000, I never encountered driver issues with this one so far… do you this this may be the cause?

      Maybe you could check under the BIOS/UEFI settings.

      I already tried but found nothing useful. Also, I don’t recall this type of issue with Xorg, I should check
