Cypress Touchpad/Trackpad XPS 12 Dell

Hardware Support
1

Hi

I have old laptop and cannot activate my touchpad - Cypress.

There are some tutorials on the internet for upgrading older kernels, but I don't have any experience of adding modules to a kernel myself.

However, maybe there are some ready-made solutions or add-on packages to get Cypress working.

The laptop also has a touchscreen, which is probably problematic, as older kernels had a problem with using two touchdevices at the same time.

In short - help is needed :slight_smile:

Hi and welcome to the forum.
Could you give me a more detail of your laptop?

[edit]
I searched other forums and the latest information was from 2015.
Perhaps not the same laptop but it uses Cypress Touchpad:

Hi

Laptop is Dell XPS 12 (2012 year)

https://www.dell.com/support/home/en-ee/product-support/product/xps-12-l221x/drivers

If correctly understand, then cypress touch uses cyapta driver
https://cateee.net/lkddb/web-lkddb/MOUSE_CYAPA.html

there is a driver here, but I have no idea how it should get into the kernel.
http://manpages.ubuntu.com/manpages/focal/man4/cyapa.4freebsd.html
and here
https://lwn.net/Articles/506273/

Frenchpress link talks about downloading a new kernel, but the example is based on a 32 bit kernel :slight_smile:

Which you can still try with Zorin 15 (32bit).
It is still under the support.

[edit]
I checked the links you provided:
This cyapta driver should be already included in the kernel:

found in Linux kernels: 3.9–3.19, 4.0–4.20, 5.0–5.15, 5.16-rc+HEAD

we are using kernel 5.11 in Zorin 16.

I wondered the same... And tried searching. And failed.
Thanks for succeeding.

While we know it is already in the kernel, we still do not know why it does not work on this laptop.

Does this laptop have a switch to turn it on and off ?

Michel - what you mean?

Laptop has usual power button - separate options to switch touchpad off it does not have.

My laptop has a button to enable and disable the trackpad.

That is an awesome looking lappy you have :star_struck:

Some of my laptops come with network switches (for WiFi and Bluetooth) but none of them have a trackpad switch.
