So I installed KDE Plama on my Arch Linux machine (paru -S plasma) but it came with flatpak which I don’t use so I removed it (paru -Rns flatpak-kcm), now after reboot the system become so unresponsive and some softwares didn’t even start (I install all of my softwares from the AUR) I had to hard shutoff every time it stop responding, So I’m wonder if flatpak is essential to Plasma functionally? PS: the softwares that actually start are the one shipped with Plasma
For now I switch to Cosmic DE until I know what causing it
https://archlinux.org/packages/extra/x86_64/flatpak-kcm/
Looks like its only optionally required by plasma-meta. I’m not familiar with it but it looks like a GUI for editing settings rather than something fundamental so I’d be surprised if uninstalling it is the source of your issues.
Flatpak kcm is the permissions control panel. link. With the n switch, you may have removed the dependencies, some of which look vital to me.
