Bug ID: 464045
Summary: startkde on systemd: safeguard agains already started
plasma session in another user session
Classification: Plasma
Product: ksmserver
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: m...@mwsys.mine.bz
CC: plasma-b...@kde.org
Target Milestone: ---
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
