How much memory is enough for 1? Back on Fedora 32, on a system with close to a year of uptime (it was attached to my TV), gnome-shell consumed nearly 20GB of RAM on a 32GB system! And I rarely interacted with it (outside of watching the occasional concert on it). Most of the time was spent on the lockscreen, with the TV on a different input.

Perhaps this falls outside the category of "any memory condition"... :)

Though, it was responsive. :D

Needless to say, I think 1 is harder than expected. Fedora has made some recent changes on the OOM killer front though, perhaps those are closer to what you're interested in.
