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.
My 2026 Linux experience:
External display: just works
Screen rotation: just works
Webcam (internal, external): just works
Audio (internal, external, Bluetooth): just works
Bluetooth: just works
Wi-Fi: just works
Ethernet: just works
WWAN (integrated cellular modem): just works
Printing: just works
I have not tried it from my laptop, but I do it via an Intel NUC, via Lyrion Music Server, to a mix of Squeezeboxes and Sonos / Airplay 2 speakers all the time!
@neil ah, yeah, from a streaming conversant app/server isn’t so bad.
But capturing audio from a random app on the machine and casting it is still way harder than on macOS/iOS. You realise how much work goes into that when you have to roll it yourself with pipewire and chromecast sink daemons 😳
@WiteWulf I will happily take our word for it!
I do it via "wireless HDMI" quite regularly, I guess, but I don't think that that is quite what you have in mind!
