The entire Linux graphic stack isn’t ready yet for HDR, so while gamescope might support it you won’t be able to use it yet.

Personally I use the infinity for Reddit app and this is disappointing as it’s my favorite app but I wouldn’t pay a subscription for it. Although I do understand why he/she is doing it I am still disappointed.

So you do have solutions like teleport which handle SSH authentication but they require external tools. My advice would be to add password authentication to your SSH key and then just use the same SSH key everywhere. It’s not as secure which is true but in my opinion as long as you have good security you will be fine.

(Another solution would be to make an ansible script which generates a new key every X days and distributes them to the servers using acces given by the old key and then removing that old key from authorized keys)
