I haven’t yet been able to determine precisely what advantages I would gain from an atomic version of Fedora, but a recommendation in another thread has prompted me to go straight for that version (Atomic).
If I have to rule out Silverblue and Kinoite because of this RAM issue, that leaves three options : Budgie, COSMIC, and Sway.
It seems to me that these others DEs were selected by Fedora because they all work exclusively with Wayland :
Can you tell me, please, if I’m right ?
The good news is that Budgie and COSMIC are lighter than GNOME and KDE.
Apart from that, I don’t know how these 2 DEs differ, or whether one is more interesting than the other (maintenance, security, ergonomics, etc.). User feedback would be welcome…
(This site provides a comparison of the hardware resources required for some DEs, but it does not mention COSMIC).
