Public bug reported:
I have installed Ubuntu 18.04.4 on my new Lenovo IdeaPad S145-15IIL, after
previously having the same problem in Ubuntu 16.04.6. The touchpad (ElanTech
0633) is not working.
>From notes/discussions in:
>https://askubuntu.com/questions/1049787/lenovo-ideapad-330-touchpad-not-working,
> it seems to me that the problem is that my touchpad id is not listed in the
>ubuntu kernel, and so ubuntu doesn't recognize it.
Running 'xinput -list' doesn't show the touchpad.
By running 'sudo acpidump | grep -C3 -i elan', I can see that my ElanTech
touchpad id is 0633.
1) My ubuntu release: Ubuntu 18.04.4 LTS (18.04) - fresh install
2) My kernel version (uname -srv): Linux 5.3.0-40-generic
#32~18.04.1-Ubuntu
3) Expected behaviour: ubuntu boots up -> mouse cursor can be controlled
by the touchpad, and it should respond to touchpad clicks and scroll
gestures.
4) Actual behaviour: ubuntu boots up -> mouse cursor can NOT be
controlled by the touchpad, and it DOES NOT respond to touchpad clicks
and scroll gestures at any point in time.
