Control brightness on OLED displays

system76-oled's Issues

Installation Instructions

I tried to install on my Ubuntu 20.04 machine and needed to install the following other packages first:

sudo apt install libxrandr-dev libx11-dev libdbus-1-dev
sudo make install

It might be nice to include this info in the readme. Hope that helps!

Noticble increase in CPU utilization when changing screen brightness

Not blocking for release, but I notice(via top) that a gnome-shell process surges to around 30% utilization when changing the screen brightness which seems quite high.

Issue/Bug Description:
I have a Gigabyte Aero with the 4k OLED panel and brightness controls do not work. I hoped that they would work since System76 released a laptop with a 4k OLED panel and I'm presuming (probably incorrectly) that it's the same Samsung 4k OLED panel that is found in most laptops with that description.

I'm able to get it working with a xrandr workaround. I went as far as creating a utility to manage it (https://github.com/nerdo/xrandr-brightness) but that comes with its own issues like it not being a true brightness adjustment and some weird flickering going on.

Steps to reproduce (if you know):

Expected behavior:

Other Notes:

Could you explain how to turn off the default brightness switch?

I installed this package and try to change the brightness, but I get the effect of freezing when I press the keys. I installed this package and try to change the brightness, but I get the effect of freezing when I press the keys until i use the keys again. Thus, I think that both the old and the new applications which responsible for the screen brightness are enabled, do you know how to disable the default on Pop!_os ?

Top brightness levels effect colour quality.

While testing Oryp7 with the OLED unit, I noticed that reducing brightness from the max setting did not effect brightness, but did change the colour balance. While this isn't critical, it also isn't - I believe - intended behaviour.

At the highest brightness values, it feels as though colour saturation is increased, and white values decreased. The first three or four decrements seem to slowly arrive at closer to expected colour values, and there after, the display dims as expected.

Currently, I cannot confirm this behaviour beyond Oryp7. The first ten or so seconds of the following video demonstrate this (admittedly not brilliantly) with the remainder being the full brightness decrease for general reference.
