So, as my username suggests I'm noob at this. I was running Ubuntu just fine on another laptop and this is the first major issue I have been unable to solve myself with a bit of googling.

I have tried the suggestions here which result in errors when rebooting:

errors

I also tried GRUB_CMDLINE_LINUX_DEFAULT="i8042.nopnp=1 pci=nocrs quiet splash"

After a reinstall and editing /etc/default/grub once again, I am no longer receiving the error above, but the touchpad is still not working. Here are some images including what /etc/default/grub looks like, output from sudo grub-update and xinput:

I cannot use screenshots as I don't have a mouse for this device and find it difficult to navigate using only the keyboard. Sorry.

It's a bug in kernel v5.15: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1970056

To solve this issue, upgrade your kernel version to v5.18 from mainline or look for tutorials online how to do that. Its really simple. Kernel v5.18 has no such problems.

However, it's not known how much time it will take to fix this in kernel version coming in ubuntu 22.04 which is v5.15
