By factory default setting, the touchpad is not detected at all even if I have `ig4_load="YES"` in `/boot/loader.conf`. However, when I switch the touchpad option in BIOS from 'Advanced' to 'Basic,' kernel started to see it as `psm0: model Synaptics Touchpad, device ID 0`. Hence I am using it under 'Basic' mode for now. (might not be related to the above) Also, this laptop also has a key combo (fn + F7) to enable/disable the touchpad; while the key combo does work on killing or reviving touchpad, kernel spits these messages every time I do that: ``` acpi_ec0: EcCommand: no response to 0x84 acpi_ec0: EcCommand: no response to 0x84 acpi_ec0: GPE query failed: AE_NO_HARDWARE_RESPONSE ``` So my understanding is that the `acpi_ec` driver expects something from hardware in return to a probing but could not get what it wants? I have no clue at all as I could not find any info on `acpi_ec`. Can anyone tell me what is happening? I'm running amd64 r339274 at the moment. Thank you, -- Hyun Hwang
