How can I turn off screen? None of the answers here helped me. I tried sudo vbetool dpms off but that failed silently and the screen remained on.
This is a headless Ubuntu server installation on a laptop. I don't want screen turned on all the time as I access this server via SSH remotely.
edit: solved it by using izx's answer in here This is not what I was looking for but at least I have nothing on the screen now.
I guess Ubuntu server means we are talking console only. Check the manpage to setterm and try the following command:
setterm --powersave powerdown
