Like the subject states, I had XFCE installed and working fine prior to installing MATE from the repos.
Now I can't go more than 10 minutes watching a video without the screen blanking out, like a screen saver is active.
I have set all power options to for monitor to NEVER, disabled and uninstalled all screensavers and still have this issue.
When using the power-manager in MATE it asks for Authentication to save my settings, which apparently it is not.
I have uninstalled mate-power-manager, no change, uninstalled XFCE-power-manager, no change.
I only have mate-power-manager installed right now.
I need to know how to get the screen from blanking out at all.
