If RPI boots on console, type
startplasma-wayland
I can't get plasma to run from a console without first starting labwc. I try running...

Code:

export QT_QPA_PLATFORM=waylandstartplasma-wayland
... but it results in wall of errors in the journal starting with...

Code:

Sep 18 06:12:24 jpc kwin_wayland_wrapper[1350]: No backend specified, automatically choosing drmSep 18 06:12:24 jpc kwin_wayland_wrapper[1350]: kwin_core: Failed to activate /org/freedesktop/login1/session/_33 session.

Given the "Maybe another compositor is running?", one would think that running labwc would cause problems, but its the only way I can get plasma to run.
