Mint 20: Touchpad Doesn't work

[Liel Almog]

Hello, I started using Linux Mint 2 months age. I've install Linux Mint 20 Xfce. Two days ago, after normal usage the touchpad stopped working, I searched all over the web - 15 tab at min, and found nothing that helped me.
I gave up and installed Linux Mint 20 Mate and the same issue is appearing and my touchpad is not reacting
NOTE - In the setup when you boot into the USB the mouse is working
NOTE - whenever I touch the touchpad the keyboard stop working, only after a restart it works again

I'll be VERY grateful if I could use my touchpad again

If you need anything else please let me know so I'll update the post

Thank You

Any chance you hit the keyboard F4 button or FN + F4 as that will enable/disable the touchpad on this Lenovo

And I've tried F4 and FN + F4 and it does not solve it
Sorry for that delay ...

Mint 20 is a relatively new release, and it seems to have problems with some laptops, especially with video drivers and trackpads. What I'd do is download the ISO for Mint 19.0 and make a Live USB and boot with that to see if the problem was Mint-version related. If the trackpad doesn't work with 19.0 it isn't version related. Sometimes there are hardware settings in BIOS, including for trackpads. If your BIOS hasppens to have such settings, and the default is 'Advanced', you can change it to 'Basic' (or something similar) and see if that works.

Mint 19 is supported until 2023

So, I had some rough some time on reinstalling and I wanted to know why it suddenly stopped working.

I've tried again what you proposed and when I heat the F4 key on the lenovo side (before linux mint), the touchpad did work, so I've done some more tries and the result was that everytime I turn the computer on (after shut down or reboot) I need to press F4 again or else it does not work.

So my last question is: Do you know how can I change the settings back so it would enable it by default?
Or that I am doomed to press F4 again ?

Problem solved on Dell Latitude E6400 with the latest update ! I also had a very bad response from the trackpad : the scroll function was unusable. The last last update included some firmware updates, and it is now working much, much better. Not perfect, but it is a great improvement ! Everything else, including volume and function keys works perfectly on this laptop with Mint 20. Even the standby works flawlessly : it resumes without any problem even after several days.

Sorry, I edited this post because I made a mistake : My trackpad always worked. Only the scroll function did not. However, check again ! The firmware update might have solved your problem too.
