I'm typing this message on my Dell XPS 13 9310. I'm really happy with it, specifically the 9310 model, not other models.
- The volume, screen brightness, and keyboard brightness buttons all work great.
- Bluetooth and wifi work great.
- Touchpad and touchpad gestures work great. It's also a decent size.
- The FHD display has no scaling issues with any apps or any distros.
- The keyboard and overall build quality feel nice.
The one thing that doesn't work great is the webcam. It turns on and captures video... except it's really dark. Although, I haven't tried running Wangblows on this, so maybe it's Dell's fault for picking bad hardware. Anyway, I just use an Opal Tadpole webcam and that works great. Happy to answer any questions about this laptop! I use Arch, btw, with GNOME. Zoom, Google Meet, Discord video calls and screen sharing all work as well.
If you're serious about this requirement:
DPI/screen resolution doesn’t cause scaling issues
then I would avoid Framework. I recently sold mine after daily driving it for about 1 year. My biggest complaint was the high DPI display. It will 100% cause scaling issues. You will have blurry apps and/or tiny text, 100%. People will suggest that you add a ton of config or switch distros—neither of which will actually 100% solve the issue—or use different apps—which you can't always because alternatives may not exist. If you want to use arbitrary software like hexchat which is GTK2, DO NOT buy a Framework laptop. 🙅
