It a Slimbook Katana. Everything works as it should with Ubuntu 16.04,
but Devuan has some rough edges. Here is the harware info, if that helps.

The xbacklight utility, as mentioned earlier, does not work so the
archlinux link that Ralph provided probably does not help. Though if I
can find the right numbers to use, I can give it a try.

   Section "Device"
       Identifier  "card0"
       Driver      "intel"
       Option      "Backlight"  "intel_backlight"
       BusID       "PCI:0:2:0"
   EndSection

Based on what's below, what should I use for "BusID" there?

Regards,
Lars
