Steam deck has HDR support now, which means HDR support for AMD gpus on linux will improve at accelerated rate going forward. Nvidia users (me included) can can only look with envy I guess.
Is HDR generally unavailable on Linux right now? I primarily game on a Windows desktop but I'm considering trying to make my next build in a few years the equivalent of a "Steam Deck Console" but I've been trying to anticipate issues that might make it too limited or frustrating to use.
If you have an AMD GPU, the upcoming KDE Plasma 6 will have experimental HDR support. Or you can use gamescope (a compositor made by valve for steam deck) as your login session which will launch steam in big picture mode (afaik you can't run other apps except steam in this desktop session).
I was able to grab a limited edition one almost 2 hours after release time. Was clicking through carts dozens of times and purchase pages about 5 times, what a mess.
I'm dying over this. I preloaded my steam wallet, left a meeting early, and started spamming the buy button the second it released. Couldn't get the purchase to go through for 30 minutes so I'm panicking the whole time. Turns out 5 hours later it's still in stock rofl.
From what I could observe of the launch, it looks like they decided to not put all the stock up to grab right away, and added it little by little to spread out the load and give people more time to get a chance to get the limited edition. It actually got "out of stock" multiple times already.
