So i have an HP Pavillion 15 Gaming laptop on which I recently tried to install ubuntu. But the main problem that i faced was that the touchpad wouldn't work at all. I switched over to pop os and manjaro and in both of them the touchpad was working fine in the live environment but after installation, it stopped working again in both of em. Can anyone help me out with this?

I have had the same issue for pop os. Solution to not working touchpad on pop os was:
sudo kernelstub -a "i8042.nopnp=1 pci=nocrs" Pop os use kernelstub instead of grub
https://support.system76.com/articles/kernelstub/
what i8042.nopnp=1 mean
i8042.nopnp [HW] Don't use ACPIPnP / PnPBIOS to discover KBD/AUX controllers https://www.kernel.org/doc/Documentation/admin-guide/kernel-parameters.txt
I have the same problem with HP pavilion 15.
according to this link https://forum.artixlinux.org/index.php/topic,1666.0.html
I tried these three methods:
first method:
sudo su nano /etc/default/grub insert "psmouse.proto=bare" in line GRUB_CMDLINE_LINUX. like
GRUB_CMDLINE_LINUX="psmouse.proto=bare" then update grub (you can replace fedora by your distro name like ubuntu)
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg or
grub-mkconfig -o /boot/efi/EFI/fedora/grub.cfg and reboot.
second method:
sudo su nano /etc/default/grub insert "psmouse.proto=imps i8042.reset i8042.nomux=1" in line GRUB_CMDLINE_LINUX. like
GRUB_CMDLINE_LINUX="psmouse.proto=imps i8042.reset i8042.nomux=1" then update grub (you can replace fedora by your distro name like ubuntu)
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg or
grub-mkconfig -o /boot/efi/EFI/fedora/grub.cfg and reboot.
third method:
sudo su echo -n 0x01 > /sys/devices/platform/i8042/serio2/crc_enabled or
echo -n 0x01 > /sys/devices/platform/i8042/serio1/crc_enabled 
- If I understand you correctly, none of these worked, and so this is not an answer to the question.tripleee– tripleee2022-11-07 18:12:26 +00:00Commented Nov 7, 2022 at 18:12
One wired solution that I found was that if you stop the system to boot directly to GRUB and instead of that if you just press the key that loads up the boot selector of your bios(in my case F9), the problem just did not occur. And apart from that on a pure arch installation I didn't even need to do that.
lsusb. Second, by "it stopped working" do you mean that it worked at some point? Also: is there any F button on your keyboard for dis-/enabling the touchpad?
