Not counting the Steam Deck, since KDE isn’t actually turned on while you’re running games.
Normally I’m a Gnome guy, but I’m building a tiny low power portable computer and wanting to keep resource utilization low, so I’m investigating other options.
I’m using WMs for 10 years now. Started with Openbox, currently running Bspwm for quite some time. Eyeing on River but not switching to Wayland yet thanks to Nvidia.
I just stick to Gnome to avoid problems in gaming specifically, but obviously Plasma works great as well on Steam Deck.
You could give LXQT a shot, which should be QT-compatible, and maybe require less fussing with if you do run into an issue. Xfce or Mate might be options as well, but not as lightweight.
Not trying to start an argument, just curious on your perspective. What makes gnome seem like windows? I really can’t see it myself. For me KDE Neon feels pretty much the same as windows 10 but with more control and customization. Gnome feels kinda more like Android - everything hidden and big ol icons and doesn’t use the whole nested window configuration system
No DE, but i3-gaps as WM. Been working great for 5+ years.
not a de, i use hyprland.
