On many Linux OSes the brightness setting is an integer between 0 and 1000 and available at runtime in /sys/class/backlight/backlight/brightness and stored at shutdown and loaded at boot from /var/lib/systemd/backlight/platform-backlight:backlight:backlight by systemd-backlight@backlight:backlight.service. Changing the brightness setting can be done at runtime, for example over SSH, by executing as root <code>echo 500 > /sys/class/backlight/backlight/brightness</code>. The stored brightness setting can be modified using another system, by mounting the root filesystem of the system you want to fix and by executing <code>echo 500 > [MOUNT LOCATION]/var/lib/systemd/backlight/platform-backlight\:backlight\:backlight</code>. | On many Linux OSes the brightness setting is an integer between 0 and 1000 and available at runtime in /sys/class/backlight/backlight/brightness and stored at shutdown and loaded at boot from /var/lib/systemd/backlight/platform-backlight:backlight:backlight by systemd-backlight@backlight:backlight.service.

==== How can I contribute regarding the WiFi and Bluetooth firmware? ==== | |||
The PinePhone uses [https://files.pine64.org/doc/datasheet/pine64/RTL8723BS.pdf Realtek RTL8723CS] for its WiFi and Bluetooth connectivity. Unfortunately, just like the other Realteks ''([https://en.wikipedia.org/wiki/Comparison_of_open-source_wireless_drivers see more info])'' - this RTL8723CS chip requires a proprietary closed-source binary blob firmware. For those who have the capability to reverse-engineer the Realtek firmware of this chip to create the opensource replacement, resources like [https://libreplanet.org/wiki/Group:Hardware/research/e-readers/Kobo/Aura_H2O_Edition_2#Firmwares this] and [https://8051enthusiast.github.io/2021/07/05/002-wifi_fun.html this] could be a great starting point for your further research. | |||
