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.
Thanks,
