I finally separated some overkill hardware from my server rig (an RTX 3080 and a Ryzen 5800X3D) and put them in their own chassi. Installed Arch, again, of course. The server got a “new” Ryzen 5700G , which apparently is a repurposed laptop APU.
A few years ago, I used to fire up my desktop environment (dwm on X11) and launch Steam from a pseudo terminal.
On my reborn gaming PC, could I skip installing a desktop environment and still play games on Steam? Will it run directly from the console like - for instance - mpv does?
The purpose would be to minimize any overhead from dwm and X11. Which sounds ridiculous now that I “say” it out loud, because it’s negligible, but still. My question still stands.
I am not sure that is fully true. Or at least not fully explained. The Steamdeck has a full KDE environment installed and it uses this when in desktop mode. But steam is not running in big picture mode in front of this.
KDE is not running at all when in the game mode of the Steamdeck. In that mode it uses a compositor written by valve called gamescope. Switching between these is effectively logging out and back in again to switch the compositor.
Also it now has a way to run the desktop as a nested session in game mode but that is winning kwin inside gamescope.
