Brightness fix on System 76 Oryx Pro
Backlight Fix System 76 Oynx Pro (2018) GTX1060 update 04/22/2023
System76 put out excellent docs on this while I was running another Linux distribution. This works great on my older Oyrx pro. I get working hybrid graphics with keyboard back-light and screen brightness control. Plus all the other System 76 goodies all work. I am running Garuda.
Note: I removed all the previous instructions.
Simply follow the instruction at https://wiki.archlinux.org/title/System76_Oryx_Pro#Installation
If the above page changes or go missing here is a copy below. Here is a screen of what I have installed for reference.
It is recommended to install everything in the list below.
There are also “-git” versions of many of these packages, if you wish to be bleeding edge.
system76-power AUR (needed for System76 switchable graphics and charging thresholds)
system76-firmware-daemon AUR (seems to be needed for things like audio to work right)
For whatever reason, these packages are prone to breaking. It would be nice if someone would be willing to provide a System76 repository with prebuilt binaries.
Several of these are bundled in the Pop!_OS kernel. Building that kernel for Arch would get all the functionality of those packages in a single step. As well: there is some functionality in the Pop!_OS kernel that you can’t get elsewhere; meaning that, without it, our Arch installs are deficient.
Once you have installed the above, you will need to tell your computer to use them.
Enable the following services: (source)
To make sure all drivers are being loaded correctly, run system76-driver-cli; this will automatically add necessary rules to /etc/modprobe.d, and execute mkinitcpio.
Note: As of 2021-04-06, this creates a malformed s76-i915-mkinitcpio.conf file, and a redundant (if you have system76-power.conf) system76-driver_i2c-nvidia-gpu.conf file. As such, this step may be skippable, for the time-being. Nevertheless, there is a known solution for the malformation: simply append 1 to options i915 in s76-i915-mkinitcpio.conf. (source)
Install the following:
firmware-manager AUR (required if you want to know when there is a BIOS update available)
system76-firmware AUR (required if you want to update your BIOS)
To check your current BIOS version and whether there is a new version available, run firmware-manager as root. Keep in-mind that this is a GTK application, so you need to be running X or Wayland for it to run. (It has no CLI — it does not even respond to –help.)
To update your system to the latest firmware on the next boot, run system76-firmware-cli schedule.
