[Power/Brightness] Integrate external monitor brightness controls #428
Comments
This definitely would be nice to have. We'd need to decide how to handle multiple brightness devices.
|
I guess key bindings could trigger the display where the mouse is. And there could be an option to control all monitors at the same time |
I would like to personally see something like monitorian's controls on windows, except a bit more sleek, A single brightness control with a dropdown menu perhaps, drop down to control each monitor individually, and when not dropped down, a single slider to control the brightness of all monitors in relation to the brightness set by the individual sliders. https://github.com/emoacht/Monitorian monitorian for reference, in the readme they have a video showcasing it working key bindings can be just for the "global" control in this case |
I see
That may be awkward with a slider? That also mentions a couple issues with certain monitors, unsurprisingly. Not sure how consistently to expect things to work with DDC/CI. Does any OS or desktop environment currently expose it prominently, by default, for all monitors that support it? |
Maybe this is useful: daitj/gnome-display-brightness-ddcutil#137 "Response times with ddcutil are slow - use DDCControl DBUS service if available" |
So it can be faster if some persistent service keeps open a DDC connection? That may be doable. |
This seems like the best way to expose the brightness and max brightness for now. In the future we may want to expose multiple brightness devices (pop-os/cosmic-applets#428). It would also be possible for client to not require the daemon and use sysfs and udev/netlink directly, but if we use DDC for external monitors we'll need to handle that a daemon as well.

The above KDE plasmoid allows users to change external monitor brightness which is very useful but also not very easy to install and does not integrate into KDE's native brightness adjustment sliders.
Ideally brightness adjustment of monitors would be a native feature akin to laptop screen brightness adjustment - COSMIC having this functionality by default would be a welcome improvement over competing DEs.
