Screen blanking / sleep under LXQt

Myostoox tries to inhibit screen blanking during video playback via D-Bus
(org.freedesktop.ScreenSaver, then org.freedesktop.PowerManagement.Inhibit).

Under LXQt (Lubuntu), these services are often missing: this is not a playback bug.
To prevent the screen from turning off during a movie:

1. Settings → Power Management (LXQt) (lxqt-config-powermanagement)
2. Extend or disable screen blanking / sleep
3. Optional: install a D-Bus-compatible screensaver provider

ServiceUnknown messages related to ScreenSaver / Notifications are silently ignored.
