Comment 9 for bug 1861925

I'm using stock Ubuntu _Mate_ 19.10. Do you think that some other Ubuntu derivate would be OK?

I have tried the stock kernel 5.3, 5.5, 5.6rc1. I will just try your kernel! Thanks!

Some more infos:
-if the brightness == max_brightness => the display is at max brightness but it does not flash.
-if the brightness < max_brightness => the display brightness is not stable (is flashing). the brightness is jumping back and fort to the value brightness and max_brightness
