Please both test the attached driver module and check if: - keyboard backlight reading/writing over sysfs works - changing the fan_mode, usb_charge, reader_mode and fn_lock sysfs attribute works - reading and writing the battery charge limit works You can use https://docs.kernel.org/admin-guide/laptops/lg-laptop.html to f= ind out more about the individual sysfs attributes in question. --=20 You may reply to this email to add a comment.
