@nprofile1q... @nprofile1q... @nprofile1q... @nprofile1q... KDE Plasma is built to run as part of a far different userspace. It's not relevant to whether GrapheneOS is a Linux distribution. Linux isn't glibc, systemd, Wayland, PipeWire and KDE. It isn't the XDG desktop standards. Linux is a kernel and Linux distributions are the operating systems using it as a kernel.

Android apps are Linux apps. You can't easily run those without using AOSP. It's the same thing the other way around. Both are still Linux.
