Thinkpad T14 Gen 5, touchpad not detected

[Timothée Jaussoin]

Hi,

I just installed Debian Testing on my new Thinkpad T14 Gen 5 and I found
out that the touchpad is not actually detected by the system.

I have nothing in dmesg or xinput. However it is fully functional in
other Live USB distros (Fedora and Ubuntu LTS 24.04, they have the same
6.8 Linux kernel).

Here is my current hardware https://linux-hardware.org/?probe=13318ed64a

Here is the dmesg in Fedora:

[ 5.398935] input: ELAN0676:00 04F3:3195 Touchpad as
/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-ELAN0676:00/0018:04F3:3195.0001/input/input8


[ 5.480290] input: ELAN0676:00 04F3:3195 Touchpad as
/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-ELAN0676:00/0018:04F3:3195.0001/input/input11

I don't have those lines in my Debian dmesg.

If you need some more information I'd be pleased to share whatever is
required :)

Regards,

You might look at the installation logs. /var/log/installer/

Is there something in particular I should look for ?

I would look for some of the identifiers in those dmsg lines you showed
earlier. See if the touchpad was detected but rejected. That migh give
you a clue as to why it was rejected.

Maybe it's the same issue as the one posted very recently under the
subject:
