Ubuntu – Lenovo Touchpad issue 20.04

20.04lenovosynapticstouchpadxorg

I decided to swap from Windows to Ubuntu 20.04 (I'm a newbie) and I found a problem with the touchpad.

uname -r gives: 5.4.0-33-generic

xinput gives:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ PS/2 Logitech Wheel Mouse                 id=15   [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)]
    ↳ Video Bus                                 id=8    [slave  keyboard (3)]
    ↳ Power Button                              id=9    [slave  keyboard (3)]
    ↳ Sleep Button                              id=10   [slave  keyboard (3)]
    ↳ Lenovo EasyCamera: Lenovo EasyC           id=12   [slave  keyboard (3)]
    ↳ Ideapad extra buttons                     id=13   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=14   [slave  keyboard (3)]

It shows the touchpad as PS/2 Logitech Wheel Mouse.

xserver-xorg is already the newest version (1:7.7+19ubuntu14).

What I've tried:

I installed first the binary:

xserver-xorg-input-synaptics_1.9.1-1ubuntu1_amd64.deb

No problems, but the touchpad still not working.

I'd appreciate help to fix this issue; I know that it is known issue, and probably the solution is in front of me, but you can appreciate I'm new to Ubuntu.

Best Answer

I've removed xserver-xorg-input-synaptics, unplugged the auxiliary mouse and restart the laptop.

The touchpad is recognised and the main functions working.

Thanks Pilot6 for the help.
