Ubuntu 20.04 Elantech touchpad not working

  • 772

I've recently installed Ubuntu 20.04 on my laptop only to find the touchpad didn't work, it is recognized in xinput and is turned on in settings. Which drivers can I install to make it work? (HP Pavilion 15 Gaming, Nvidia GeForce GTX 1050, AMD Ryzen 5)

Output of Xinput :

  1. Had the same issue on my HP Pavillion running Ubuntu 20.04. I spent two days looking for a solution.

    The first thing that worked for me was editing the /etc/default/grub file:

    GRUB_CMDLINE_LIN UX_DEFAULT="quiet splash psmouse.proto=bare"
GRUB_CMDLINE_LINUX="i8042.reset i8042.nomux i8042.nopnp i8042.noloop"

    The link below has the full procedure: https://medium.com/@barcelos.ds/how-to-fix-touchpad-mouse-not-working-in-linux-operating-systems-b328bb43b4c5

    After making those changes I could not use two-finger scrolling. To get that working I had to update the Linux kernel to version 5.10

    The link below is what I followed to update the kernel: http://ubuntuhandbook.org/index.php/2020/12/install-linux-kernel-5-10-ubuntu-linux-mint/

    Hope this helps.

  2. This is a kind of a bug in Ubuntu 20.04 where xorg-synaptics is in use when it shouldn't be.

    This can be fixed by

    sudo apt remove xserver-xorg-input-synaptics

    The touchpad should start working with libinput after a logoff or reboot.

  3. I had this problem. In the end what fixed it was upgrading the linux kernel through the HWE:

    sudo apt install linux-generic-hwe-20.04

    This brings in newer device drivers from the linux 5.11 kernel.

  4. I found this post that said to go into the boot menu and select the linux boot and it worked for me. However, you have to do this every time you reboot.

  5. I've been using Ubuntu since 08.04 but don't consider myself 'knowledgable' on the subject. I have noted however that I suffered the same issues with my new HP laptop when I replaced Windows10 with Ubuntu 20.04. No touchpad detected ergo just no touchpad! I recently decided to dual boot Win10 & Ubuntu but the problem persisted until today. I selected UEFI Firmware Setup from the Grub menu. This took me to Windows Boot Manager where I selected Ubuntu.This took me back to the GRUB menu where I selected Ubuntu. Hey Presto, fully functioning Touchpad with one and two finger scrolling etc. Hope this helps someone else with similar setup to gain functionality. My motive was simply to get back to Ubuntu as I tired of Windows very quickly and just wanted to come 'home'.
