From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Every once in a while I think I'll drop my mix of all those GTK/Gnome-based apps plus some Qt apps, and switch to a full KDE desktop. More coherent. Uniform look etc.

I just tried Q4OS yesterday but it runs under Xorg. Isn't wayland the default for KDE these days? Which distro should I live-check?

Another thing, I noticed that something called ksyslogger iirc consistently eats CPU. A daemon that keeps up with everything that's happening. Is it possible to disable this without breaking KDE, or otherwise make it as lightweight as, say, a simple Openbox desktop?

Using Falkon under a Plasma desktop was a great experience though.

BTW, does KDE have a good equivalent for all the usually important apps, e.g. a full-fledged mail client?

Which distro should I live-check?

Fedora KDE, CachyOS, Debian. One of those, depending on your needs.

You can rice KDE Plasma easily. Check why ksyslogger uses so many resources, it's not normal. You can get a full Plasma desktop with under 400MB of RAM usage and under 0.5% CPU.

I use Thunderbird as mail client, as Kmail doesn't really cut it for me.

under 0.5% CPU

Surely this depends on the CPU?

On a Thinkpad T430s with a Intel Core i5-3320M, i.e. 2 cores with 2 threads each at 3.3GHz max., ksyslogger ran at 3-5% CPU. This was in a live environment which I shut down after tweaking it for about 30mins, so IDK, maybe it would've settled down evtl.?

You mean ksystemstats? You can theoretically disable it completely. Plasma depends on ksysguard but you can probably just run plasma-shell without it. Never tried. There have been comparisons between "lightweight" DEs and Plasma where Plasma didn't consume more resources than say Xfce.

Thanks, I guess it was ksysguard what I saw eating CPU in Q4OS.

I tried CachyOS Plasma live yesterday, it ran so much lighter! Idling at ~1%, that's basically the same as my current (fully riced) Openbox system.

However, the live system is very barebones.

I researched CachyOS and I approve so far. Even the ArchLinux community doesn't seem to hate on it. Have to boot it up again and sniff around under the hood.

This might just be my stepping stone back to a fully fledged DE.

I recommend boot partition snapshots. Other than that, CachyOS is very fast and optimised.

Hey, thanks for recommending CachyOS Plasma. Been using it a few days now and I'm very happy.
