Bug ID: 483259
Summary: Suppress systemd wall messages at reboot/poweroff
Classification: Plasma
Product: plasmashell
Version: 6.0.1
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: Session Management
Assignee: plasma-b...@kde.org
Reporter: cogebok...@hisotyr.com
Target Milestone: 1.0
SUMMARY
Since version 251, systemd's default behavior is to print wall messages on
calls to systemctl poweroff/reboot/halt. These wall messages follow the format
of:
"The system is going down for reboot NOW!"
Plasma intercepts these wall messages and displays them as a toast notification
with associated sound.
This is undesirable behavior - it adds unnecessary noise to the shutdown
process, and a user may misinterpret the notification as an actually important
notification they missed while shutting down their device. A user does not need
to be informed of a shutdown or reboot they just triggered.
STEPS TO REPRODUCE
1. Shut down or reboot device from plasma
2. Watch/listen for wall message notification in plasma
OBSERVED RESULT
Wall message toast notification appears and notification sound moments before
plasma itself shuts down.
EXPECTED RESULT
Plasma shutdown process should be clear of extraneous notifications.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 6.5.6-zen2-1-zen
KDE Plasma Version: 6.0.1
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
ADDITIONAL INFORMATION
To resolve this issue, all calls to systemd poweroff/reboot/halt should have
the "--no-wall" flag appended, likely in ksmserver or libkworkspace. This has
been available since systemd version 253. See poweroff(8) man page for
additional info.
