BYD touchpad on Librem 13 rev1/Librem 15v2 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
IMPORTANT: This only applies to laptops with BYD touchpads, notably Librem 13 rev1 and Librem 15 rev2.
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
Restart for this to take effect.
