Yeah, support is really not fully landed yet on snapdragon-x laptops.

I picked up a lenovo slim 7x last year, and It's still not an 
'out of box' experence. There's a flow of non upstreamed patches
getting things working.

I've been using jhovold's tree. So for example for the 
not yet released 6.13 kernel:
https://github.com/jhovold/linux/tree/wip/x1e80100-6.13-rc6
53 non upstreamed patches. :( 

( I build a fedora rawhide kernel rpm from that at:
https://copr.fedorainfracloud.org/coprs/kevin/x1e80100kernel/ )

Even that isn't enough to get things fully working, you need
to pass the correct devicetree from that kernel in grub or the
like.

With that, everything works here except for the webcam and
speakers.

So, yeah, those patches will have to land in the mainline kernel
and then people will need to sort out the devicetree handling
before things will just work. ;( 

So you likely made a good call for now...
