Hi, Corentin! Some remarks on your patch which upto now works great for me! 1.) configuration seems to have a "circle": Warning! Found recursive dependency: ACPI_ASUS ASUS_LAPTOP ACPI_ASUS 2.) The dependency X86 makes it necessary to enable generic X86-optimizations. Is that intended? 3.) With recent BIOS versions the implementation of the value for the Touchpad LED has switched. So an "echo 0 > .../led" results in the led to light. Maybe there is a way to deal with that in kernel space. But I think we already had that discussion some months ago.
