How fast is Plasma on old hardware? (slrpnk.net)

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've used KDE on a Thinkpad T60, it's about 17 years old, has 3GB of RAM, and a Core Duo. It ran surprisingly well. Replacing the HDD with a SSD can also make a noticeable difference, so you should consider that if you haven't already. I also turned off a lot of the animations and effects for better performance.

Interesting. SSD is not an option as this is not really used and has a huge 1,8TB HDD.

And it runs very fine for its job.

I wish plasma had a "energy saving mode" where all this fancy stuff is disabled. Transparency, blur, animations etc.

While tedious, those effects can all be turned off in *"Workspace Effects" or whatever it's called. Not at my laptop to check.

I know. But as you said it is rather tedious.

Is there a CLI interface for these settings like gsettings on GNOME?

@boredsquirrel
You can edit the config files that live in XDG_CONFIG_DIR/kde

The only effects relevant for performance are blur and background contrast. Turn those off if you feel the system is slow, maybe increase the animation speed and you're done

[–] [email protected] 0 points 4 months ago (1 children)

You cannot disable animations right? Setting the speed to max seems equivalent, but do you know if it actually turns something off?

[–] [email protected] 0 points 4 months ago

Setting the speed to the max does turn them off
