I'm running Ubuntu 20.04 on my Thinkpad T495s and I wanted to enable adaptive brightness. However, the automatic brightness is missing from my Settings/Power.
I tried to google and found this article which mentioned using
gsettings set org.gnome.settings-daemon.plugins.power ambient-enabled true
to enable automatic brightness but it doesn't seem to work.
Any ways to fix the system settings? I'm also open to using third-party apps if I can't use the system settings.
