Disable sleep mode - Is this RatOS issue or my touch screen?

My touch screen goes blank after 10 or so minutes and the only way I can wake it back up is to unplug its USB/Power connection. I searched the pi forums and saw people referencing DPMS, but those commands return "unable to open display" so not sure what the actual issue is. I know on my linux servers the console will sleep after inactivity and those have no GDE/GUI installed. Is there some switch in RatOS to disable this or is it possible the hardware on my touch display?
