@Jhonnatan_borja you need to blacklist the hid_sensor_hubs module in Arch currently, as the ALS sensor overrides the brightness keys, even if it’s disabled in the BIOS: 12th gen not sending XF86MonBrightnessUp / Down - #19 by ConfuSomu. rmmod the hid_sensor_* drivers without rebooting to test, or add the blacklist and reboot. It should work fine then!
