Well my ASSumption that it was a video issue since the f2 and f3 keys do not increase or decrease the backlight was just that.  This issue is with e19 dimming the backlight on logout, disabling the feature solved it :)

I have narrowed it down to an issue with just enlightenment desktop, no such issue on xfce.  ctrl+alt+backspace or anything does nothing.  Will install gpu-tools and libva-intel-driver, thanks.

At the point where you log out, are you logging out of an lxdm session? Have you tried restarting X with ctrl+alt+backspace?
