Personally, I have a GUI-less server that is connected to my lan running jellyfin server and an nvidia shield plugged to the TV with an alternative launcher to get rid of ads. That way, the server consumption is low and always on and you get a good interface and a remote for the TV.
If you really want a Linux device plugged to the TV, you could look into Plasma Bigscreen, a KDE made for TV.
Actually not the first tri-folded phone, but OK
CachyOS tend to offer their own modified kernel, for gaming optimization, if I remember well. You may not be running the correct kernel.
When you look at the installation guide of the linux-surface github, there are steps for several distros. Do you plan to use your surface for gaming mainly, hence the reason to install cachy or do you plan to use it for various tasks? It may be easier to make it working on a fedora or, if you really want an arch based distro, on arch.
The end of the article misses one possible way to deal with your computer, migrating to Linux. It’s not possible for all the mass of people, but it’s still a possibility.
Your easiest way is to upgrade windows normally and if you dislike all it’s bloated software, just install Atlas OS on top of it. It’s just a software that will go through your windows and debloat it as much as possible. Simple as that. Easier done than reinstalling windows for an LTSC version. I personally have a dual boot with a win 11 with Atlas OS specifically for the software I can’t install on Linux.
You can already put your PC games on romm and your saves. You just download the game in gog and put it in romm in the windows or Linux platform (I think there is one for mac games also). If you already have romm installed, it might be easier to use it than to have a second service installed.
Right, it’s still in dev. But could be something to look at, in the future.
