It gets better too. I suppose it depends on your distro and hand ware mix as for what works out of the box.
Eg. my pure AMD Rog Zephyrus laptop worked with Fedora pretty much “out of the box” once I enabled 3rd party drivers.
It’s kinda like switching to stick shift— it’s touch weird, but once you’ve daily driven it a bit the system is second nature.
I’m unsure. I use Gnome (for ease honestly) and Fedora with Wayland, so (iirc) dynamic display stuff is a wash and I haven’t even explored yet since I just use the clamshell.
I may not be the most helpful for you :/
