That means that it worked.  You were using a chromakey video renderer 
(like Xv) and because someone had painted over the color key, you will 
never get any more video until someone redraws the window with a solid 
color key.  You can do this by triggering a repaint (switch desktops 
from then to the one with the video window or obscure the entire video 
output window then uncover it).

I'm sure this was all just testing, but remember that you don't want to 
just use xdg-screensaver reset if you're coding up the xdg-screensaver 
support.  We want to use the suspend/resume support.
