I have an HP Pavilion Gaming Laptop 15-ec0xxx with Ubuntu 20.04, and its ETPS/2 Elantech Touchpad is not working

The touchpad shows up in xinput list, and so does my USB optical mouse, the ID of my mouse (9) is lower than that of the touchpad (12). I think this means that my mouse is registered before the touchpad.
Touchpad also shows up in /cat/proc/input/devices.

I have tried the following solutions -and more I cannot find- in vain:

20.04, HP Pavilion gaming 15 laptop, touchpad not working
Elantech Touchpad not working on Ubuntu 16.04 and Arch Linux
https://www.maketecheasier.com/fix-touchpad-not-working-linux/ (Have installed all the packages mentioned)

This is the output of lsusb

  • Looking at the long history of that question, either on Linux Mint or Debian (and other distros) it seems that your piece of hardware will not work on Ubuntu... Your investigations are correct, but you'd probably won't find solutions in older versions, since the kernel has changed since then – kanehekili Sep 05 '21 at 20:25
  • Can you update your question to include the output of lsusb? This will show the device ID, which can then be used to check for compatibility on Linux-Hardware.org – matigo Sep 05 '21 at 21:20
  • I have added the output of lsusb @matigo – Shookti Sep 07 '21 at 17:33
  • What do you suggest @kanehekili? Is there any way to find out which kernel version supports my hardware? – Shookti Sep 07 '21 at 17:38
  • Also, the touchpad did work a very few times. But this was a while back. @kanehekili – Shookti Sep 07 '21 at 17:55
  • There does not seem to be a touchpad enabled on your notebook. Some HP notebooks will let you enable/disable the touchpad by double-tapping the pad in the upper-left corner. Alternatively, there could be a keyboard shortcut like [Fn]+[Key] (a key with a blue icon that looks something like a touchpad). – matigo Sep 08 '21 at 01:17
  • My laptop does not have an [Fn]+[Key] shortcut. And double-tapping on the top left of the touchpad also does not work – Shookti Sep 09 '21 at 08:18
  • My touchpad device name is no longer displayed in the output of xinput list @matigo – Shookti Sep 09 '21 at 08:18
  • If the device isn't showing up anywhere and you're unable to re-enable it, then you may have a broken touchpad – matigo Sep 09 '21 at 08:31
  • Touchpad works on Windows; dualbooting – Shookti Sep 11 '21 at 04:40
