Ok, I am asking this because I couldn't find anything on internet or S.E, or the newest post I found is from 2011..

I recently install Ubuntu 20.04 on my laptop (Lenovo ThinkPad), and I noticed that when I disconnect the Power, the screen brightness goes to 10% or something like that, so I decided to change that. I went to Settings -> Power, and I realized that the options there weren't enough, in the sense that I cannot configure different behaviors when on battery or plugged. This is what I have, so no specific configuration.

I tried to install gnome-power-preferences (expecting this), but it does not exist, neither through apt nor snap, and when I try to install gnome-power-manager it is already installed in its newest version. I ended up installing xfce4-power-manager, which comes with xfce4-power-manager-settings, which is fine.. I wanted to know if there is a way to install gnome-power-preferences, of if it was deprecated or removed some time ago.
