Onderwerp: [DNG] KDE Desktop Question
Martin, Steve,
Sorry for bringing up the initial question.
TL;DR
So you both got me to pondering KDE/Plasma Desktop loads etc, etc, etc.
I remembered I had an old lenovo thinkcentre M-93 that I had installed MX linux on for the wife sometime back. (she likes her laptop instead)
I also installed plasma desktop 5.2xxx at the time. So I pulled it out for some experiments. Updated and off to test.
Here are some specs. Attached is the whole machine specs as a file for reference.

System:
Kernel: 6.1.0-21-amd64 [6.1.90-1] arch: x86_64 bits: 64 compiler: gcc v: 12.2.0
parameters: BOOT_IMAGE=/vmlinuz-6.1.0-21-amd64 root=UUID=<filter> ro quiet splash
Desktop: KDE Plasma v: 5.27.5 tk: Qt v: 5.15.8 wm: kwin_x11 vt: 7 dm: LightDM v: 1.26.0
Distro: MX-23.3_x64 Libretto May 19 2024 base: Debian GNU/Linux 12 (bookworm)

Mobo: LENOVO model: SHARKBAY v: SDK0K17763 WIN 1801925231317 serial: <superuser required>
BIOS: LENOVO v: FBKTCCAUS date: 11/21/2016
CPU: Info: model: Intel Core i5-4570T bits: 64 type: MT MCP arch: Haswell gen: core 4 level: v3
*************************************************************************
At idle no apps running cpu = 2-3%
Add firefox no browsing cpu = 6-8%
Add 2 different open webpages = 11-13%
Add Libreoffice writer and start word processing cpu = 2%
Open second firefox browser and stream 1 youtube video cpu = 28-32%
Stream 2 youtube videos at same time cpu = 30-45%
Add Thunderbird cpu = 13-27%
Idling with apps open cpu = 2-5%

This is respective of my personal useage.
So several things I noticed with this build, although a lot of K-apps are installed:

- Akonadi is not installed
- Nepomuk not installed
- Baloo is not installed
- Kmail works without Akonadi or pulling Akonadi in. I started it but didn't set it up as I normally just use thunderbird
- cpu useage isn't necessarily additive as more apps are opened.

So maybe they have changed a few things since I used it last? I don't know how it is all incorporated but it is similar to Void and Devuan only in the fact that systemd is not default init.
So a possible low resource hungry desktop for those who like KDE?
