BYD touchpad multi-touch support?

byd driver is disabled by default in newer kernel versions, enable it by putting

echo -n "byd" > /sys/bus/serio/devices/serio1/protocol

to /etc/rc.local.

cat /etc/rc.local should give you following:

#!/bin/bash
echo -n "byd" > /sys/bus/serio/devices/serio1/protocol

Make sure the script is executable.
