Hello Roman,
I like your delightful Sculpt story ;-)

- On Sculpt, most/all? internal displays report only their native
resolution. On the XPS this is 3200 x 1800 and I can't force a lower resolution. Although under Linux, xrandr reports a bunch of supported resolutions from 3200 x 1800 down to 640 x 360. Does the intel_fb_drv under Genode intentionally reports and supports only the native resolution?
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.
- Instead of installing Sculpt directly on my current laptop I consider
to buy a new XPS 13 (9370). It has a Killer 1435 wireless module featuring a Qualcomm Atheros QCA6174A chip which seems to be supported on Linux by the ath10k module... Has someone any experience (or assumptions) whether there's a chance that it will work on Sculpt (right now or in the near future)?
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).
