The brightness can be controlled by writing to these files. But these
files do not exist if xfce4-power-manager isn't installed. So it seems I
need this package (or an equivalent in another DE) to be able to set a
decent brightness.
Hmmm, are you sure? I have a text only install of devuan Jessie on an
external usb drive (no GUI at all), and these files do exist for me on
that install when I use it on my laptop.
Probably I made a mistake. Now, after removing xfce4-power-manager,
xfce4-power-manager-data and xfce4-power-manager-plugins, the 3 files
are still there.
Thanks.
