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.
Why not try it for yourself on Linux mint first by installing plasma? Plasma 5 is available on mint - I believe Fedora has plasma 6.
I use plasma 6 on my Opensuse Slowroll laptop and plasma 5 on my LMDE desktop.
Overall, I’ve found plasma 6 to run slightly better (I was on plasma 5 on Slowroll too for a long time).
Once you install and try plasma 5 on your current install, that will be a much less disruptive way to see how well it works for you.
After ricing, both plasma 5 and 6 are pretty similar on my setup. The cube desktop effect isn’t there by default on plasma 5 of course.
