Hello,

I am having trouble to have my touchpad work correctly, on my laptop Dell Inspiron 7506 2n1 with Ubuntu 20.04.

In order to perform a left-click, I need to touch the pad 3 times (instead of 2 usually). I can't perform a right-click by touching the pad with two fingers, nor can I scroll this way.

I noticed that the command "xinput list" returns the following :

Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ CUST0000:00 04F3:2A4B                     id=9    [slave  pointer  (2)]
⎜   ↳ PS/2 Generic Mouse                        id=13   [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)]
    ↳ Sleep Button                              id=7    [slave  keyboard (3)]
    ↳ Integrated_Webcam_HD: Integrate           id=8    [slave  keyboard (3)]
    ↳ CUST0000:00 04F3:2A4B                     id=10   [slave  keyboard (3)]
    ↳ Dell WMI hotkeys                          id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=12   [slave  keyboard (3)]

 Disabling the "PS/2 Generic Mouse" (with "xinput disable 13") disables the touchpad, so it is id=13. But I can't understand why it is not recognized as a touchpad? Can I do something to have it detected properly?

 

Thanks
