Bug ID: 454755 Summary: Screen cycles 22 seconds off, 4 seconds on, only with Wayland Product: Powerdevil Version: 5.24.5 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: cantabile.d...@gmail.com Target Milestone: --- SUMMARY When powerdevil turns off the screen after X minutes of inactivity, the screen constantly turns back on for ~4 seconds, then stays off for ~22 seconds, then turns on again for ~4 seconds, and so on indefinitely. The backlight stays off, though. This only happens in the Wayland session. The screen stays off solidly in the X11 session. This suspicious message appears in journalctl every 30 seconds, but not all the time, and not just when the screen is off: Jun 02 18:32:52 home xdg-desktop-portal-kde[203852]: xdp-kde-background: GetAppState called: no parameters STEPS TO REPRODUCE 1. Pick the Wayland session when you log in 2.

Turn the screen towards a light source, otherwise the difference is not really visible 4. Wait OBSERVED RESULT The screen continuously turns on and off. EXPECTED RESULT The screen should stay off.
