I am running Red Hat Enterprise Linux 7.4. I have done a minimal install so that I don't have X11, xorg, xset or anything x related installed. I am trying to keep the monitor from going blank. When I log in I can run the following command which does the trick:
setterm -blank 0 -powerdown 0 -powersave off
However, when I put that in a script to run at boot time (I call the script from rc.local for now) it doesn't work. I am trying to keep the screen on even before a login. Any suggestions?
