That's been my experience with Arch as well. I've only seen a handful of actual breakages in my time (using consistently since 2016), and there's _always_ a good discussion with a manual fix available within a few hours, or a few days if you want to stick to official update channels.
Plus KDE Plasma has become such a joy to use! I repurposed my T530 as a media center with a wireless keyboard and it's been a fantastic experience
The physical setup is very simple: just the laptop wired through miniDP to the TV, laptop sits behind the TV on a little wardrobe and has its screen turned off. I have various handbraked movies (not for distribution, only my personal usage) and shows that I view in VLC, plus a gigabit Ethernet connection that is more than enough for HD streaming.
I keep it simple, just have a standard desktop install of Arch with Plasma. Lets me also do work on the machine, writing code here and there, checking emails etc. The living room setup is much easier on my back for extended work sessions as compared to my office chair.
Same reasoning here, my back is not well and even though I am starting physiotherapy in a few days, I am looking for a setup I can actively practice from a couch-like position. Even bought a very nice and sturdy (and comfy) folding bed. And will soon order a lap desk.
Makes me a bit salty because the Steelcase Gesture is an absolutely EXCELLENT chair and I paid a lot for it but... health is more important. Hopefully I will be using it more in the future if my physiotherapy progresses well.
Thank you for the anecdote. I am pondering Manjaro with XFCE but might look at KDE Plasma as well; a lot of people praise it.
YMMV but the snide remark is definitely unjustified.
