Wake Remote Monitor Console

This afternoon I’ve been using screen -x on my main machine into a console monitor next to me for a super quick multi monitor set up while I configure a server.
Everything worked perfectly except the monitor displaying the console screen on my server kept turning off every so often and I would have to touch the actual keyboard attached to it to wake it again.
This drove me insane and I still haven’t found the correct solution to keep it from blanking by default. I’ve tried a few things but I’m not currently sure what combination of them if any is correct, I’ll make sure to report back here when I know.
In the mean time I do have a solution for waking a remote monitor to share that eases the pain somewhat.
To wake up a monitor displaying only a console ( not an X session, that’s another thing entirely ):
echo -e ‘\033[9;0]\033[14;0]‘ > /dev/console
This worked perfectly for me on CentOS6, ymmv on other assorted distros.
