Hi Steev,

I believe that I remember reading at some point that the touchscreen
issue on the x13s was related to some probe deferral issues. If so,
try adding this patch series from Javier to see if that helps the
situation:

https://lore.kernel.org/lkml/20221116115348.517599-1-javierm@redhat.com/

Javier separately encountered a probe deferral issue when enabling a
Snapdragon-based Chromebook on Fedora that caused him to work on that
patch series.
