  • There is no Ubuntu version 20 or 20.0

  • Ubuntu has releases that use the year format (they are snap only such as Ubuntu Core 20 and are designed to be used headless so no screen or keyboard, nor mouse), and products that use the year.month format which are available in desktop & server format. There is no month 0; and a 20 product has no UI as it's intended to be controlled remotely so finger scroll makes no sense for a Ubuntu Core 20 product. Ubuntu Touch you've highlighted is a different product again - for phones hasn't reached an OTA-20 yet I believe

  • "2 finger scroll automatically stop working and I've no idea why?" you can disable/enable it on some machines by tapping the top right corner of the touchpad.

You may have tried this already - but in settings (menu at the top right - click on the little down-arrow), there's a Mouse and Touchpad submenu - check that two-finger scrolling is enabled. Mouse & Touchpad menu

I hope this helps.

    I can't see TouchPad option in my setting? Aug 12, 2021 at 8:20
  • Sorry that didn’t work. The menu I showed was from my laptop - when I did it from my desktop the menu didn’t give any touchpad options so the menu that comes up depends on the hardware installed. I’m sorry I don’t have any other suggestions.

  • there is no way we can make it good, i've tried so many things but still no result, just re-install the ubuntu and it will be good, I guess it's a bug Oct 10, 2022 at 8:36

Using the answer found here: https://www.pcspecialist.co.uk/forums/threads/solved-ubuntu-20-04-2-the-touchpad-on-my-initia-15-6-does-not-work-properly.78128/

  1. sudo nano /etc/default/grub

  2. comment out the old line and replace with

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nocrs"
  1. sudo update-grub & reboot

Finger scrolling should continue to work
