The feature will not appear in the GUI if you're running a kernel version that doesn't support it (or on ~50% of laptops that also don't support it). You can force the setting off unconditionally with:
gsettings set org.gnome.settings-daemon.plugins.power ambient-enabled false But the setting is different for each user, so the above command will only stop it happening on the desktop but won't stop it happening on the login screen (user 'gdm'). -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1938477 Title: Screen brightness changing randomly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1938477/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
