Hello, tried to run linux OS on this laptop and found these problems: - only working fn keys are multimedia + sound - can't control brightness, keyboard backlight, sleep, touchpad disable I found out my keyboard id is 0x1866. I looked into the source code of the kernel and saw there is no keyboard with that id. I found that there are 3 types of keyboard USB_DEVICE_ID_ASUSTEK_ROG_KEYBOARD1,2,3. I replaced in file hid_ids.h the id of the USB_DEVICE_ID_ASUSTEK_ROG_KEYBOARD1 to 0x1866, compiled kernel and rebooted. All fn keys are working but keyboard backlight is still not working. Brightness is working if I install nvidia-driver-415, i have only nvidia card in this laptop acpi_listen reports that fn keys for kbd backlight are working also OSD is present but nothing happens. From journalctl i can see this message: Asus failed to request functions: -75. I think it is because i just changed the id but the function request has different vector for the backlight to get the functions ? Can you help me solve this ? This is my first bug report, don't know what you need, i will provide anything you need to fix this. Thanks.
