an extrenal mouse makes my mouse pointer work giving temporary relief.

Now on kernel 5.8
observation is that the touchpad sometimes doesn't work. So far,
shutdown and remove AC then restart fixes it every time. This was true
on 5.7 too.
Something goes wrong with hardware initialisation?

I'm also affected by this it seems (although currently using Manjaro).
Both Kernel 5.7.9 and 5.8rc5 result in the Touchpad randomly deciding not to
work on boot.
If it works, everything seems fine, though.

I had the same problem, the touchpad was not even recognised.
I changed the BIOS setting to "only UEFI" (no Legacy support) as suggested by
gustavekkj.
Now it works! Or at least most of the time: sometimes when booting it stops
working again, but (up until now) a reboot fixes the problem.

The only problem is ... I didn't make it work, so I have no idea why it started

Confirmation bias: I installed ubuntu again with secure boot. Didn't
update kernel. Didn't do anything in bios apart from only uefi. Now i
only need to open and close the bios then the touchpad works. If I don't
do it it stops working. This bug is weird.

I found a weird work around updated the kernel to 5.7.1.
Then i disabled legacy support uefi only.
Then secure boot then booted up. Ubuntu told me it couldn't.
Then disabled secure boot and then it worked.
When it stops working redo these last steps in BIOS makes it work.

Hi there,
My problem is same as yours.
I have an Ideapad 81YH with intel i7 chipset. I installed ubuntu 20.04
with kernel 5.4 and touchpad doesn't seem to work as well.
2-3 days ago I modified the grub in /etc/default, it made my touchpad
working for a few boots. Unfortunately, it's gone..
IDK
What I learned by using Linux is patience. In the meantime I use a
bluetooth mouse. Works fine, but you have to activate bluetooth with
another device ;-) Lucky, that everything else is doing well.

perhaps the same issue?!
The main culprit was CONFIG_PINCTRL_SUNRISEPOINT that provides an
interface that allows configuring of PCH pins and using them as GPIOs.
Apparently the touchpad port needs to be unlocked by the signal raised
by PCH's GPIO pins, so this module is required for it to work.
