Kernal paramiters not shown

I've had an issue in the past where mt touchpad wouldn't work or would stop working randomly, i fixed this by going to /etc/default/grub and changing i8042.noaux to i8042.nopnp then updated grub and fixed it, reinstalled due to a couple off issues and now theres no kernal paramete.

Here's how it looks now  GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet splash " if i add i8042.nopnp into the line and reboot it disables my touchpad.

Re: Kernal paramiters not shown

Which is absolutely normal after a reinstall. i8042 was always a parameter you will have added yourself. FWIW just adding that to that line will not do anything yet unless you regenerated your GRUB config with grub-mkconfig changing anything there will not have an effect.

What I do not quite get, apparently your touchpad works without the parameter and breaks with it, why do you think you need to have it in the first place?

my touchpad will work and then randomly stop working

If disabling PNP breaks the touchpad completely, just don't disable it and focus on the original problem.
1. does it still exist
2. does the dmesg reflect the loss of the touchpad w/ some message/oops/crash/… ?

I haven't seen anything on dmesg however check it after it's happened  again.
