Hope you can help.
I have a weird problem.
When I boot up my laptop (with Sparky 7 Orion-Belt fully updated, XFCE edition) the power manager for display is not working most of the time. But when I go into power manager and disable and re-enable display power management again, then it works again until the next boot up.
So the display doesn't blank until I disable and re-enable display power management in the power manager
