Quickly & smoothly changing monitor brightness?

This has turned out to be more tedious than I thought. I did the usual looking up tools to use, and found they use ddci, like ddcutil and ddccontrol, but they’re very slow. Before setting them up, KDE’s brightness slider did software brightness, now it does hardware brightness but now takes a whole moment with each brightness, I can’t smoothly slide it back and forth like I can on laptops. I have a Dell G3233Q connected via USB For USB ports and DisplayPort.

I have the same question, for me the KDE slider works like 1/6 of the time. Do you have an Nvidia GPU?

brightnessctl is useful, can do percentage-wise. With some shell math you can also make buttons to increase and decrease it

Ddc/ci brightness changes are very often animated by the display firmware, so doing it fast is rarely possible.

You can however disable ddc/ci in the display settings if you’d rather have software brightness.
