I have a little bit old Samsung XE700, but it works awesomly well with Linux Mint 18 Mate. Now I did some research on how to get the last amount of perfection out of it, and learned about backlight, acpi_als and iio-sensor-proxy.
All these components are working well!
But they don’t seem to be interconnected. Does Mate support adjusting the backlight brightness upon input from als sensor somehow?
this wiki helped a lot in the past with previous Linux versions, where fewer features worked out of the box. The great thing is, that meanwhile everything all hardware features are supported on a clean install already!
But the automated setting of the backlight, depending on input by the light sensor is not described there (=usage of these features in concert) - I suppose this is a task for the display manager; I found hints for supporting this with Gnome 3, but not with Mate.
