I also couldn’t get sddm to work from the KDE settings. I changed the sddm.conf file manually and I’m using the catpuccin theme. The Arch wiki helped (as usual).

Yeah, but the form factor of the steam deck makes it more appealing if I want to set It up in the living room

Ok. I get it now. I’ve been trying to build something cheap as a Linux gaming setup and I’ve come to the conclusion that I’m better off buying the steam deck.

I would stick with SMB and SSH(SFTP). SMB for content sharing and accessible on any device like PCs or phones. SSH, which includes SFTP, for accessing everything else on the server.

I haven’t noticed any issues. But only Plasma would be a DE. Qtile and hyprland are WM, not sure if that makes the difference.
Initially I had doubts if it would work, but so far so good.

Nice work. Why move from plasma to hyprland? Install both and login on the environment you want at any time. I have qtile, plasma and hyprland
