Hi,
Following the integration of the Enable PINCTRL_METEORLAKE,
PINCTRL_METEORPOINT modules I was able to use my touchpad properly on my
Meteor Lake powered laptop.
It was solved by installing the
linux-image-unsigned-6.9.0-060900-generic_6.9.0-060900.202405122134_amd64.deb
package from experimental.
The recent upgrade to 6.9.7 is bringing back the touchpad not detected
issue. It seems, that those modules are missing again or are not working
properly anymore.
If you need some more information I would be happy to provide them to you.
Regards
