Quoting from it: > I did check it by flashlight. Even with all available backlights drivers compiled as modules it does not work. With Kernel version 5.15.106 backlight works fine. > Kernels for Chomebook uses dtb files that have some backlight config set (used gpio), like exynos5250-snow-common.dtsi and dmesg of 6.3.4 gives some gpio warnings. Maybe cause in it. See bugzilla for the full thread and attached dmesg & kernel config. Anyway, I'm adding it to regzbot: #regzbot introduced: v5.15..v6.3 https://bugzilla.kernel.org/show_bug.cgi?id=217489 #regzbot title: Chromebook XE303C12 backlight stopped working with gpio warnings Thanks.
