Mooi dat Valve eindelijk vaart maakt met SteamOS! Voorlopig blijf ik bij CachyOS met Nix en eigen dotfiles want ik gebruik liever Plasma Bigscreen dan Plasma Desktop. Zeker nu het werkt met de Steam Controller en de afstandsbediening van mijn TV via HDMI-CEC.

Valve haalt mijn tijdrovende geknutsel inmiddels aardig in, dus wie weet stap ik binnenkort toch weer over op SteamOS…
