Appending "i8042.nopnp=1 pci=nocrs" to boot parameters worked for the
touchpad issue on the Lenovo V14-IIL .
Following are the steps I've followed:
1.) Open the file /etc/default/grub for editing, for example by running
sudoedit /etc/default/grub
2.) Add to the line beginning GRUB_CMDLINE_LINUX_DEFAULT: "i8042.nopnp=1
pci=nocrs" so that it reads:
GRUB_CMDLINE_LINUX_DEFAULT="i8042.nopnp=1 pci=nocrs"
** If other parameters are there between the double quotes, it may be OK
to leave them.
3.) Save the file and exit
4.) Run this command to update the GRUB configuration:
sudo update-grub
5.) Reboot

Bug description:
Greetings,
tried 3 different distros nothing seemd to work, also tried at lest 5 boot
parameters and some other hacks that worked on 14-IML for example but nothing
worked.
Only driver that's missing is touchpad and it's not even showing in
the list.
Current distro: Ubuntu, tried on manjaro and kali
Kernel version: 5.7.1-050701-generic

Also cat /proc/bus/input/devices shows everything except touchpad.
If you need any more info please let me know, I bought this laptop for linux
only and it's really annoying when you cant use touchpad.
