I just got through purchasing a ideapad game 3 Lenovo laptop, and i cannot get the touchpad to work at all. I installed Ubuntu 20 LTS, and it did not work,
I read that if you install 21.X it would work, so I did. . .that failed too.

I am not very good on Linux I read something like this:

i8042.nopnp=1 pci=nocrs Installed in the grub.

Will this work for me? If it does, where do I install it?
I know how to edit the grub, but that is the extent of my knowledge.

Any help would be appreciated.

Still no response. . .

This is where I added the information. . .Not sure if this is correct or not.
Can anyone help me with this, or give me an idea?

I have no idea whether those kernel boot parameters will work for you or not, but where you have added them is correct. BTW, it should be "i8042.nopnp=..."
Save when done, and don't forget to run
then reboot.

FWIW, a similar thread...
https://askubuntu.com/questions/1249...g-ubuntu-20-04

Looks promising...

Thank you folks.. I tried it, but it failed. . .
Anything else I can do?

There was only one who replied so far - me

Can you confirm current boot parameters?
Review the following troubleshooting guide, and if necessary file a bug report...
https://wiki.ubuntu.com/DebuggingTouchpadDetection

Here it is. . thank you very much for your patience.

BOOT_IMAGE=/boot/vmlinuz-5.11.0-34-generic root=UUID=0311989e-135a-4436-bbcb-7025acad5f91 ro i8042.nopnp=1 pci=nocrs quiet splash vt.handoff=7

Ok, that looks ok. There are other i8042-related parameters that can be tried, but it really does involve experimentation, and it is usually symptomatic of hardware quirks that need sorting out within the kernel. It may be that a more recent kernel needs to be tried, especially for new hardware.

You might want to share the following information...
One block of output will pertain to the touchpad device. That is the only information of relevance really.

Here's some information about upgrading your Ubuntu distro to the latest kernel..

The pertinent section...
This long bug report
suggests support for this hardware (04F3:3140 chipset) exists with kernel 5.11 onwards. My advice is for you to try a recent mainline kernel (ref post #9 of this thread).

Right now, I am running
5.11.0-34-generic

Do you think I should upgrade my kernel? Even though it is already at 5.11.0-34-generic?

Worth a shot IMHO.

Thank you. .

I installed 5.14.1

Mouse pad still doesn't work. . .

Any other suggestions?

Bug report?
