For better or worse, Linux often takes on the responsibility of working around firmware bugs. This is a real issue that affects multiple Asus laptops; you'll have no touchpad input upon reboot from any OS that drives the touchpad in "generic hid" mode (e.g. older version of Linux, some embedded OS, etc). If the sleep is really that controversial, we could make it specific to the ELAN1000 model that is the one in question here? [KT]:We can consider to control specific module, our FW engineer is checking it and confirm which part number for ASUS should adopt work-around. we will reply you once we confirm. Thanks Daniel
