Description mike 2023-01-09 11:42:01 UTC 
systemd allowes only one graphical-session.target per user, not per session. This will not change and is by design (never mind that it is called -session, not -user)

a clean and easy way might be checking if graphical-session.target is already running before starting QStringLiteral("plasma-workspace-%1.target").arg(platform)


STEPS TO REPRODUCE
1) run startplasma-wayland or startx that launches startplasma-x11 on a tty/VT
2) do the same on another tty/VT

OBSERVED RESULT
The second session does not start, instead only a black screen is shown

EXPECTED RESULT
Output a message that says that there is already a graphical session running and thus the start of another session is prohibited
