The new intel driver accepts my graphics adapter shown as
8086:116 so this one should be kept in the list.

However I cannot find a way to dim the lights. The brightness
is stuck at the maximum level, which is unbearable.

The functions keys for adjusting the brighness (Fn+F2 / Fn+F3)
have no effect. I guess I have to hook something to the
functions keys, but how can I do that ?

With Gnome, there was a brighness control under "Power
Management", which worked at least on Nvidia graphics, but
there is no power management any more with Mate.

Please point me at proper documentation for adjusting the
brighness.

With the vesa driver, Fn+F2 / Fn+F3 showed an on-screen
brightness control (with no effect on actual brightness),
but with the intel driver I do not get this control, so I
think there were inappropriate hooks with vesa and the hooks
are missing with Intel.
