Thinkpad T14 Gen 3 Mystery: ELAN0678:00 04F3:3195 Touchpad

I've had this laptop running arch for about a year now. About a month ago the touchpad stopped being recognized and is not detected, see the output of libinput list-devices: https://gist.github.com/jacksonatl/0727 … 55423834d8 However, when booted to the installer iso it is detected, see output: https://gist.github.com/jacksonatl/8dca … e944ec4bb1
Even more mysteriously, this same pattern is true for several distributions, OpenSuse-Leap 15, OpenSuse-Leap 16, Fedora 40 and Fedora 41. When running the installer ISOs the touchpad is detected and works as expected but when the distribution is installed to disk, suddenly the touchpad is not found. Any help would be much appreciated!

Which kernel and libinput versions on the live disk vs what's installed? Can you reproduce on the LTS kernel? Any errors in the journal?

sudo journalctl -b | curl -F 'file=@-' 0x0.st

libinput --version 1.27.1
uname -a Linux thinkpad 6.12.10-zen1-1-zen
jouralctl http://0x0.st/88Xb.txt
From LTS:
libinput: https://0x0.st/88Xu.txt
jouralctl: http://0x0.st/88Xu.txt

Using custom built archiso with linux 6.12.9 and zfs 2.3. No libinput installed but running systemctl start gpm enables the touchpad on the iso.
