[fedora-arm] F20 remix on Cubieboard 2 - video stops responding once screensaved

[Robert Moskowitz]

On the F20 remix from:

Works well enough, but once the monitor goes into screen saver mode, it 
does not come back.

I waited an hour to log in, and the monitor stayed active that whole time.

I logged in as user, and left the kybd/monitor alone until it dropped 
into screensaver (and locked session) and now it is not responding.  I 
tried typing my password in as that is typically what state you are in 
at that point, but still no response.

I have vnc running right now and logged in and that is working as is the 
serial console, so the system is not locked.

Where may I look for what is causing this?  Other than turning off 
screensaver mode.
