Touchpad not working

Support

Hello everyone,

I decided to dual boot my HP 15S-eq1023np that has an Elan touchpad with Manjaro 21.2.6 Kernel 5.15 and Windows 10.

Before, I was using Manjaro in a VM testing it out and it was going fine. When I decided to install Manjaro, the installation process was going flawless and the touchpad was working. But when I restarted the machine in Manjaro the touchpad was not working anymore.

I already reinstalled the system 3 times and confirmed that it only works on live usb and the kernel versions are the same.

Also tried to change GRUB and added i8042 parameters among a lot of other things.

Xinput in live usb shows elan touchpad but in native OS it doesn’t. After tinkering with GRUB it was listed as PS/2 Generic Mouse.

Concluding if a given hardware works with Linus - in this case a touchpad - cannot be done in a virtual machine.

Then it should work after installation as well.

Though it should suffice - one could suspect that libinput is not optimal for the touchpad.

While not directly related you may get an idea from

After adding other i8042 options to GRUB it now lists as an ‘ETPS/2 Elantech Touchpad’ but still no move. I followed the links you sent and installed synaptics driver. Since I had a file named 30-touchpad.conf with libinput and 10-synaptics.conf the touchpad was using libinput, but after renaming it to 70-synaptics.conf now it is using synaptics driver.

Unfortunately no move still.

Here is Xorg log about touchpad:

Just a quick update: I tried installing Endeavour OS and openSUSE and none of them work as well. Same result, it work on the installation process but not in the native OS.

Another update: apparently I need to press F9 to select the boot device every time it boots and select Grub but I don’t know if there is any other solution that doesn’t involve that.

If anyone knows one I would really appreciate it.
