Bug ID: 440882
Summary: Screen Energy Saving does not respect
SimulateUserActivity when XWayland is used
Product: Powerdevil
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: fores...@sonic.net
Target Milestone: ---
SUMMARY
The org.freedesktop.ScreenSaver SimulateUserActivity dbus method is supposed to
reset screen blanking timeouts. It works for both the screen locker and the
Screen Energy Saving feature when used in X.Org desktop sessions. However, in
XWayland sessions, it works only for the screen locker: The Screen Energy
Saving feature ignores SimulateUserActivity on XWayland, and the screen
therefore powers off when it should not.
STEPS TO REPRODUCE
1. Start a KDE Plasma 5 XWayland desktop session. (I used KUbuntu 21.04 in my
test.)
2. In KDE Settings: Screen Energy Saving, enable the feature and set "Switch
off after" to 1 minute. (Note: You might need real hardware, not a VM, for the
option to appear.)
3. Start a shell script that runs the following command every few seconds:
qdbus org.freedesktop.ScreenSaver /ScreenSaver SimulateUserActivity
4. Sit back for a minute waiting for the energy saving mode to activate.
OBSERVED RESULT
The screen powers off, ignoring the SimulateUserActivity calls.
EXPECTED RESULT
The screen should not power off. It should respect the SimulateUserActivity
calls, just as it does in an X.Org session.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu 21.04
KDE Plasma Version: 5.21.4
KDE Frameworks Version: 5.80.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
Problem exists with XWayland sessions, but not X11 sessions.
