Hello Roman,

I like your delightful Sculpt story ;-)

>From my experience current laptop panels do not support display
resolutions beyond the factory setting. The illusion of a range of
display resolutions provided by the Linux drivers (and also the
VGABIOS) is implemented by setting up some hardware scaler which
converts the pixels from the used resolution to the native one. Our
driver port does not initialize this feature yet.

We had an offline discussion about this topic some weeks ago and as
far as I can remember the effort to enable ath10k should be
reasonable. This does not mean its quite some work esp. on the
debugging side if the added driver's requirements exceed the currently
provided emulation environment. Maybe you can join forces with Hinnerk
in the debugging phase at least. Please feel free to open a feature
issue on GitHub for the developments as I'm aware of at least one
other potential user (who's not me).
