Since we’ve seen this multiple times before the probability of PureOS running on your machine is highly unlikely. If you want to try PureOS out and see what it looks like and how it works then do so in a VM or Just use then Gnome version of Debian, looks and feels the same, it’s mostly just not PURE.
PureOS is optimized/specialized to work with Purism hardware while only using hardware driver who’s driver code is open source and I think that’s not the case with your hardware.
