Title:
  Lenovo Flex 5 Touchpad Not Working

Status in ubiquity package in Ubuntu:
  New

Bug description:
  I recently installed Ubuntu 22.04 LTS as a dual boot on my Lenovo Flex
  5 14ARE05 and the touchpad doesn't work.

  The Touchpad is not displayed in settings. It is also missing from my
  xinput, and libinput list-devices. I've checked the BIOS and there
  isn't a toggle there either.

  I have tried various kernels (5.19.17, 5.15, 5.14, 5.4, 6.02, and the
  latest 6.04) in mainline.

  I changed the grub to:
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.proto=bare"
  GRUB_CMDLINE_LINUX="i8042.reset i8042.nomux i8042.nopnp i8042.noloop"
  also each separately and with nomux and/or noloop set =1.

  I've turned the psmouse on and off with sudo modprobe.

  I'm not sure what else to do, or is there not a fix for this yet? I think ultimately the issue lies in xinput and libinput not showing the touchpad at all, but I can't find a fix for that either.

  hardware that is installed is the MSFT0001:00 04F3:3140 mouse
