Perhaps it is because I have used Linux for quite a long time now, and it did not always work so well, but I still smile when I plug my laptop (Debian, Gnome, Wayland) into a Thunderbolt dock via USB-C shaped connector, and its display appears on multiple 4K monitors within a couple of seconds.
I unplug it, and it comes back to the laptop screen.
Screen rotation on my laptop works flawlessly.
Thank you - genuinely - to everyone who has worked on making this happen so seamlessly.
@neil Magnificent, isn't it?
When I think back to those days of trying to get my damned modem working in Linux Mandrake ...
@hedders @neil Oh man, winmodems were such a pain. At least "normal" modems could be configured with AT commands... so glad I stopped using dialup in about 1999 when I got my first broadband, but I had to "support" friends and family with it for years after. Usually on windoze...
By the time Mandrake came round, broadband was a fixture in my life, so never had to wrangle modems with it. Was a good distro though - I used it up until Ubuntu Hoary Hedgehog came out.
