Is there any high-end Linux laptops with matte displays? Everything seems to be using glossy displays, which after being used to use a matte one, is simply impossible to use, especially when using the laptop outside or in a sunny room.
You can apply a third-party non-reflective screen-protector.
My guess is that the main reason many devices have reflective stock screens is that a reflective screen has higher brightness, while a matte screen is dimmer. I think most will agree that matte is preferable in actual use, but when looking at basic screen benchmarks or when looking at a bunch of screens in a hardware store, buyers are attracted to bright screens.
How well it works depends on how well you've applied it. I've seen some botched applications. Good news is that they're cheap, so you can try again with a new one. Try searching Youtube for application walkthroughs and tips.
There could be differences in protector quality as well, I've no idea about that.
Using newest XPS 15 and am really happy everything works (you have to run newest Kernel though). I am using Ubuntu. Even the Bluetooth microphone and fingerprint work !! Haha
Macbook displays, although glossy, are generally better compared to other glossy displays with respect to reflections. Do you use your macbook in a particularly bright room/outside?
Writing this from a X1 Gen9, I wouldn't call the following "very good". Not sure if it's already fixed in new firmware (and couldn't google the support forum right away), but I had to
* switch sleep mode to stop it from getting hot while asleep;
* disable touchpad in BIOS to stop it from spinning fans while awake — great for me because I don't like it anyway and vastly prefer the trackpoint, but people not used to this consistently go wtf while trying to show something on my laptop.
I had some of these issues with the 5.17.x kernels but once I switched to Fedora 36 and 5.18.x, and updated the BIOS, the situation improved dramatically and sleep was fixed.
My Thinkpad X1 Nano also runs Linux quite well. They come with Windows pre-installed but are certified for Ubuntu. Qubes/Xen also runs pretty well, although Xen doesn't support hibernate (only suspend).
