calling X11-only function
KX11Extras::compositingActive()
Classification: Plasma
Product: plasmashell
Version First 6.6.2
Reported In:

OS: Linux
Status: REPORTED
Severity: crash

SUMMARY
powerdevil crashes XWayland session on Wayland by calling X11-only function
KX11Extras::compositingActive()
STEPS TO REPRODUCE
1. Start a KDE Plasma Wayland session without a display manager (launched from
console)
/usr/libexec/plasma-dbus-run-session-if-needed startplasma-wayland >
~/kde-sessionlog 2>&1
2. Wait a few seconds after the desktop appears
OBSERVED RESULT
Intially, previous applications are loaded and for a moment or two everything
is normal.
The session freezes and becomes completely unresponsive.
Check the session log and observe the following sequence:
```
org.kde.powerdevil: Handle button events action could not check for screen
configuration
dbus: Activating service name='org.kde.LogoutPrompt' requested by
org_kde_powerdevil
kf.windowsystem: static bool KX11Extras::compositingActive() may only be used
on X11
kwin_xwl: The X11 connection broke (error 1)
```
WORKAROUND
Confirm by renaming /usr/libexec/org_kde_powerdevil — session runs stably
without it
EXPECTED RESULT
To not freeze/hang.
