It seems, the user either has some big problems on his KDE installation or looking to shared memory usage, to begin with. Let's see what I have in the same list: 157M kwin_x11 (window manager) 392M plasmashell (desktop shell, widgets and other on screen tools) 175M krunner (macOS spotlight equivalent) 30M kded5 (settings and background daemon) 10M kactivitymanagerd (multiple activity contexts) 40M polkit-kde-authentication-agent-1 (KDE polkit bridge)) 25M org_kde_powerdevil (energy settings) 19M kdeconnectd (use mobile phone as remote control) 5M xembedsniproxy (make tray icons work) 13M kaccess (accessibility keys?) 16M ksmserver (Plasma session manager) 41M plasma-browser-integration-host (Firefox can show desktop notifications) 10M kwalletd (password manager) 6M kglobalaccel5 (global keyboard combos) 5M kscreen_backend_launcher (changing screen orientation and resolution?) 2M kio_http_cache_cleaner (?) 32K xsettingsd (apply colour scheme to Gnome applications) (Some lines omitted since they are not running on my system) On uninstalling/disabling things: - There's background services menu, which you can control which services to load. - Baloo can be completely disabled by disabling file search. - Akonadi is just "Online accounts". Add nothing, it consumes nothing. - KRunner runs on plugins. You can disable any and every plugin, which will reduce its memory footprint too. - You can uninstall any KDE feature package (at least in Debian), and these features will magically disappear from KDE interfaces. Lastly, as another user noted, KDE and Qt has a self-resizing magic, and will try to minimize its memory footprint when the system has low memory. So, you can run KDE on a 4GB system and a 32GB system. KDE will allocate more in the second system, but will evict as much as possible as the memory load increases. Witnessed this in a professional project where we ran KDE on extremely limited thin clients and saw how it behaves.

  > You can uninstall any KDE feature package (at least in Debian), and these features will magically disappear from KDE interfaces. You didn't actually try this. It makes me annoyed that you think you can go on the internet and just claim something and expect it not be verified; what a bunch of nonsense. In Debian 11.5, when one tries to uninstall any of kactivitymanagerd, polkit-kde, kaccess, then the package manager also takes out KDE as a whole.

    There are core and optional components of KDE. kactivitymanagerd is a core component, so it reverse-depends plasma, that's true. > You didn't actually try this. No. I tried this and did more. Like using Debian for 15 years, KDE since 3.5.x days or leading a Debian derivative distro's development for 5 years, and deploying that derivative nation-wide from thin-clients to heavy metal. > It makes me annoyed that you think you can go on the internet and just claim something and expect it not be verified; what a bunch of nonsense. Same here. Let's not project our prejudices to others unchecked, OK? If you want to verify my claims, my webpage is there, with links to anything and everything I do.
