Yup, and I fully expect that to be solved by end of 2024. I have already fired up Halo Infinite on NixOS with a patched kernel and have seen HDR working via gamescope. Just a matter of ironing out kinks, KDE is already in progress, I expect Cosmic to start supporting soon, too.
Are you saying all the sleep/hibernate, touch-pad, wifi, etc. issues that have plagued linux on laptops for decades at this point have now been resolved?
With Debian, the key thing is that you usually have to install the non-free-firmware package to make things like WiFi work (anything that needs a proprietary blob). This isn't done automatically.
