I've read lots of things by now about the behavior of amdgpu and backlight control but I still haven't found a way to actually achieve this:
So battery life on the V3 isn't great as we all know and I personally think the tablet's backlight doesn't go down low enough (comparing with any android/IOS tablet at low brightness makes the V3 look like the sun). Finding a way to lower the power provided to the backlight/recalibrate it in some way would fix both of these issues, right?
But how? Just setting the card's brightness value to 0 is still the (imo) the max usable brightness in regular inside usage. 100% brightness (value somewhere around 63000) is burning my eyes.
There must be some way to manually reduce the backlight power or tell the gpu to use less power when set to 0. On most machines (or maybe just intel cards), setting brightness to 0 should actually turn off the backlight entirely, but even that I could not achieve so far. I'm stumped.
