Thinkpad L480 Touchpad not working

Hello forum,

I use a 2018 Thinkpad L480. I can seem to use USB mouse but the touchpad and buttons does not seem to respond to any input.

This is the output of `xinput list`

⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
⎜   ↳ MOSART Semi. 2.4G INPUT DEVICE Mouse        id=10    [slave  pointer  (2)]
⎜   ↳ MOSART Semi. 2.4G INPUT DEVICE Consumer Control    id=11    [slave  pointer  (2)]
⎣ Virtual core keyboard                       id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard                 id=5    [slave  keyboard (3)]
    ↳ Power Button                                id=6    [slave  keyboard (3)]
    ↳ Video Bus                                   id=7    [slave  keyboard (3)]

    ↳ MOSART Semi. 2.4G INPUT DEVICE System Control    id=12    [slave  keyboard (3)]
    ↳ Integrated Camera: Integrated C             id=13    [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard                id=14    [slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                      id=15    [slave  keyboard (3)]
    ↳ MOSART Semi. 2.4G INPUT DEVICE Consumer Control    id=16    [slave  keyboard (3)]

Any help would be appreciated.
Thank You

Hopefully this helps.

sudo sh -c 'echo -n "elantech" > /sys/bus/serio/devices/serio1/protocol'

I have a L580 with the same issue and it worked for me.

Re: Thinkpad L480 Touchpad not working

If you want your mouse to work at startup, here is a systemd script
save it as /etc/systemd/system/elantech.service:

[Unit]
Description=
#After=default.target

[Service]
Type=simple
User=root
ExecStart=/bin/bash -c 'echo -n "elantech" > /sys/bus/serio/devices/serio1/protocol'

[Install]
WantedBy=default.target

And then run the following to enable the service at startup:

systemctl daemon-reload && systemctl enable elantech.service

Reboot, and voila.
