{nav icon=home, name=Main Page > icon=wrench, name=Troubleshooting > Byd driver not loaded} 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): {icon 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: {icon terminal}`sudo touch /etc/rc.local` {icon terminal}`sudo sh -c 'echo "#!/bin/bash\necho -n byd > /sys/bus/serio/devices/serio1/protocol" > /etc/rc.local'` {icon terminal}`sudo chmod +x /etc/rc.local` Restart for this to take effect.
