First, notification should not pop up as windows, they should pop up  
as notification "bubbles".

So, is the package mate-notification-daemon installed???

Secondly, I think a fallback of mate-power-manager to using pop up  
windows is a wrong approach on a missing notification daemon. There  
should be no notifications at all!!!


So..

1. Please let me know if mate-notification-daemon is installed.
2. Please install mate-notification-daemon if it is missing and let us  
know if the issue disappears then.

Greets,
Mike
