So the backlight is set to 255 most of the time (because with that value it is
stable)...
I have pressed the decrease and increase backlight buttons some times:
arg4 is different...
arg5 is 0x0 here too...

So I have tested your custom kernel. It does not fix my problem:
-if the brightness == max_brightness => the display is at max brightness but
stable.
-if the brightness < max_brightness => the display brightness is not stable (is
flashing). the brightness is jumping back and fort on the value

I'm using stock Ubuntu _Mate_ 19.10. Do you think that some other Ubuntu

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

Some more infos:

I have tried the the points 1-16 in the document

I have a Acer Aspire A315, and I was glad that the BIOS 1.15 fixed the
problems with the boot, and the WA kernel parameters were not needed
anymore. But now I have I have the next problem:
