Control backlight when using VESA driver with Intel graphics

[Michael Gmelin]

This is what I'm using on Haswell ULT (xf86-video-vesa):

pkg install git libdrm libpciaccess
git clone https://github.com/grembo/intel_backlight_fbsd
cd intel_backlight_fbsd
make install

You can then control brightness using:
intel_backlight <percent>
intel_backlight incr
intel_backlight decr

https://github.com/grembo/intel_backlight_fbsd/blob/master/README
has more details.
