BYD touchpad on Librem 13 rev1 is not recognized

Problem

There are no touchpad settings in GNOME control center.

Check

Check if the touchpad driver is loaded (execute this command in your terminal):

cat /sys/bus/serio/devices/serio1/protocol

If the command returns ImPS/2, then the BYD touchpad driver is not loaded.

Solution

Run the following command in your terminal:

echo byd > /sys/bus/serio/devices/serio1/protocol

To automatize this on every boot, create a file (if doesn't exist) /etc/rc.local with the following content:

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

The file must be executable.

Terminal command to do all this:

sudo touch /etc/rc.local
sudo sh -c 'echo "#!/bin/bash\necho -n byd > /sys/bus/serio/devices/serio1/protocol" > /etc/rc.local'
sudo chmod +x /etc/rc.local
