I've tried adding these kernel parameters in GRUB before boot placing
them just between the "splash" and "---":
i8042.nopnp=1 pci=nocrs
(according to here
https://www.reddit.com/r/linuxquestions/comments/f9h0q4/touchpad_issue_lenovo_s14515iil/fmg277m/
)
And voila!
- Touchpad is working
- Touchscreen is working
- pen/Stylus is NOT working properly - it behaves only just like if using a
finger - no additional functionality except for basic "clicking"
BUT! according to kernel documentation (
https://www.kernel.org/doc/html/v4.10/admin-guide/kernel-parameters.html
) - this is a BUG and shall be reported:
nocrs [X86] Ignore PCI host bridge windows from ACPI.
If you need to use this, please report a bug.
So... what are next steps, please?
Thanks
