I use ddcutil all the time on linux to set my monitor brightness without needing to fiddle with the OSD.

The ddcutil folks also have a great GUI btw: https://www.ddcutil.com/#ddcui https://www.ddcutil.com/#ddcui Also, if you have ddcci-driver-linux installed, then the KDE desktop lets you adjust monitor brightness from the UI. Eventually Linux upstream might get the same functionality as the out-of-tree module. https://gitlab.com/ddcci-driver-linux/ddcci-driver-linux https://gitlab.com/ddcci-driver-linux/ddcci-driver-linux

  In my experience the KDE desktop lets you set monitor brightness from the UI... and on Wayland it happens even if you don't ask it to (https://bugs.kde.org/show_bug.cgi?id=494497 https://bugs.kde.org/show_bug.cgi?id=494497). You can turn it off by "setting the `POWERDEVIL_NO_DDCUTIL=1` environment variable in PowerDevil as described in its README file: https://invent.kde.org/plasma/powerdevil/-/blob/master/README.md#troubleshooting--reporting-bugs https://invent.kde.org/plasma/powerdevil/-/blob/master/READM..."

    And here I was assuming it was changing to intel arc or display port (due to the card) or wayland (due to the driver) that causes my screens to jump to 100% brightness after they turn off. I see it still isn't fixed after 5 months so if I can't go back to X after my next update I'm putting my old nvidia back in.

      I'd recommend following the steps at https://invent.kde.org/plasma/powerdevil/-/blob/master/README.md#troubleshooting--reporting-bugs https://invent.kde.org/plasma/powerdevil/-/blob/master/READM... to disable brightness control. You can switch to X11 too, but for some reason I get screen tearing and blocky incomplete updates I haven't looked for a workaround yet. systemctl --user edit plasma-powerdevil.service [Service] Environment="POWERDEVIL_NO_DDCUTIL=1" EDIT: I tried switching to Wayland on Arc and am getting stuttery mouse cursor movement at around 36 FPS. I wonder what's wrong...
