    Question Touchpad not detected on Ubuntu 22.04 LTS. Dell Inspiron 3543.

    Yesterday, I updated ubuntu from 20.04 to 22.04, then my touchpad not worked. This is some information on my machine:
    Code:
    > xinput
    ⎡ Virtual core pointer                        id=2    [master pointer  (3)]
    ⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
    ⎜   ↳ Logitech Wireless Keyboard PID:4023         id=15    [slave  pointer  (2)]
    ⎜   ↳ Logitech Wireless Mouse                     id=17    [slave  pointer  (2)]
    ⎣ Virtual core keyboard                       id=3    [master keyboard (2)]

        ↳ Video Bus                                   id=8    [slave  keyboard (3)]
        ↳ Power Button                                id=9    [slave  keyboard (3)]
        ↳ Sleep Button                                id=10    [slave  keyboard (3)]
        ↳ Integrated_Webcam_HD: Integrate             id=11    [slave  keyboard (3)]
        ↳ Dell WMI hotkeys                            id=12    [slave  keyboard (3)]

    I found it's the problem of loose cable. Now I fixed it. Everything works fine.
