journalctl --user-unit plasma-kwin_wayland3 log locations · Linux
KDE Plasma logs to journalctl --user-unit plasma-kwin_wayland on Linux. 2 other Linux log locations are recorded below, including paths for Wayland and X11.
Paths are printed exactly as KDE Plasma writes them. Environment variables like %LOCALAPPDATA% and $XDG_STATE_HOME are never expanded, so a path can be pasted straight into a shell. Where a path differs between installer types or shipping flavours, each one is racked as its own card below - why that happens.
