Slackware 14.2 and intel i3-6100 brightness level not working

Hello! I have a problem and it is not working the brightness level, I see the level that goes up and down, but does not effect, in slackware 14.2 and intel i3-6100, I have to fix them with redshift or with f.lux on windows8 with the same problem.

Ls / sys / class / backlight /

- intel_backlight does not appear, how to load this?
I have tried all sorts of commands but there is nothing to do.
In windows8 it does not work either. I hope the translation from Spanish to English
Is acceptable

By backlight do you mean the backlight under the keys on the keyboard?

What exact make and model is your laptop?

i3-6100 processor is quite recent and it has Intel HD Graphics 530. Maybe the i915 internal driver from your kernel does not support graphics 530. I had that problem on an old laptop. The intel_backlight doesn't even appear in /sys/...

You could try installing a newer kernel.
