I have a very cool Core 2 Duo laptop here that runs Linux Mint.
And it is pretty aweful. Would love to put Fedora Kinoite (Atomic KDE) on there, manual upgrades on shutdown, minimal set of apps.
But I dont know how well Plasma works on such old hardware. It is pretty bloated and messy sometimes, Dolphin and plasmashell are my biggest worries (the whole panel and widget stuff is sooo complex).
Has anyone tried Plasma?
An alternative would be LXQt with KWin once 6.1 comes out and it has full Wayland support.
I have tons of issues on Plasma 6 with the whole thing, several bugs reported. Compared to something like cosmic panel widgets, or GNOME or anything else it just seems overcomplex and fragile. I can also imagine this results in lag and performance issues, but idk.
I mainly use an 11th gen i7 laptop :D
