I installed OS with wmi3 few months ago. Touchpad was working good. From this week my touch pad is not working any more. I googled and added 30-touchpad.conf file in /etc/X11/xorg.conf.d but its not working how to fix this?
my 30-touchpad.conf

Section "InputClass"
    Identifier "touchpad"
    Driver "libinput"
    MatchIsTouchpad "on"
    Option "Tapping" "on"
    Option "TappingButtonMap" "lmr"
EndSection

xinput list output:

First of all, run

xinput test 14

This will run a program to detect input events from your touchpad (device id = 14). After you run the command, move your finger around the touchpad to test it. You should see a bunch of text printed on the command line that looks like this every time you move your finger across the touch pad:

motion a[0]=1440 a[1]=665
motion a[1]=667
motion a[0]=1434 a[1]=672
motion a[0]=1423 a[1]=681
motion a[0]=1409 a[1]=689
motion a[0]=1389 a[1]=694
motion a[0]=1364 a[1]=698
motion a[0]=1342

xinput will print a[0] if horizontal motion is detected and a[1] for vertical movement. If there is not printed output, or if the movements across the touchpad doesn’t correspond to the printed outputs, then your touchpad might be faulty.

Have you seen:

???

4

There is no text printed in command line when i move my finger across the touch pad.

5

Yes, I tried all options in touchpad option but none of them work.

6

That means no input event was detected from the hardware.

Does it work in a live environment?

7

No, Its not working in live environment too.

8

I tried in ubuntu live environment. Seems like issue with hardware.

9

This is most likely the case. Not sure if it’s worth it to have the touchpad replaced. How old is the laptop?

10

I bought it 4 months ago.

11

From the brief search I made, it looks like there are major problems with this touchpad on linux :frowning:

12

What about the machine’s UEFI bios? There are graphical interfaces for UEFI bioses nowadays. Does the touchpad work there?

13

It’s not working.

14

Even in the UEFI bios? Then your touchpad is most likely faulty. You should have it replaced if it’s still under warranty.
