Now from Ubuntu 24.04 can change brightness using - From Ubuntu Desktop session (wayland): `sudo ddcutil setvcp 10 5 --display 1`. - From Xorg session: `xrandr --output HDMI-1 --brightness 0.5`.
The idea is that the brightness change could be done in a friendly way from the gnome screen brightness control instead of the terminal. For example, if the computer supports backlight, make the change from this class, but do it at a high level with xrandr or ddcutil depending on whether the user uses Ubuntu desktop or xorg. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1967335 Title: Brightness is not show in desktop mode To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/1967335/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
