I had to delete the mainstream kernel as I was having a horrible screen
tearing (my graphic card was not supported).
I left the kernel parameter "dyndbg='file drivers/input/mouse/* +p'"
and, although the issue still exists, it reduces the frequency of times
I need to use the "modprobe"
Is there anything else I can do?
I know Lenovo has an ubuntu forum, but hey are not very responsive...

There are two methods for touchpad in ASL code that seems to be related
to power control:
Method (TPRD, 0, Serialized)
{
P80H = 0x2E
Return (^^EC0.ECTP) /* \_SB_.PCI0.LPCB.EC0_.ECTP */
}
Method (TPWR, 1, Serialized)

So, with my usual kernel version, 5.4.0.40-generic, adding that line

It was working for a while, but after the laptop goes idle or the screen
is locked, the touchpad goes back as a generic mouse; the trick of
disconnecting and connecting it back with ```modprobe psmouse``` keeps
working though...

It is using oem2.inf
I add the line at boot, by editing the grub and adding it at the end of
the line which starts with 'linux', and I don't want to get to excited,
but so far, so good...

Sorry, I uninstalled the updated kernel; should I install it again?
Where do I configure that line? during boot?

Just tried it this afternoon.
The issue is not fixed; I'm not seeing any difference...
I'm still using the new kernel (5.8.0-050800-generic); Should I delete
it?
Any other test?

No, uninstalling drivers are unnecessary.
Only thing needs to do is to install the kernel debs.

Thanks for that.
I have a nVidia GeForce GTX 960M graphic card.
I am using proprietary drivers; I didn't need to do anything, it was
automatically installed when I first installed Ubuntu 20.04.
I've read on the page you sent me before, that I need to remove the
nVidia drivers before installing

Touchpad is still getting disconnected randomly and identified as

until is recognised again.
If you point me towards an info page I will try the mainline

I have realised that if I restart the mouse twice in a row, the touchpad
is recognised as such and starts working for a period of time.
```sudo modprobe -r psmouse```
```sudo modprobe psmouse```
Then, it is recognised back as a generic mouse and stops working.
