i have a question about monitor power management in the console environment: i use my omv NAS together with my PC connected to one screen. The NAS is connected via HDMI, the PC via DVI. After booting omv usually the console is showing "login:". After a while the screen turns black and when i press a key on the keyboard of the NAS, the login screen reappears. Unfortunately when the NAS is showing the black screen, the monitor it is not really "switched off". It is simply showing a black screen. The monitor is still switched on. This is quite annoying because when i turn off my pc the NAS keeps the monitor switched on.
From the behaviour of the NAS (when i press any key an and the login screen reappears) i think there is some kind of power management active. But i would be fine to add somethink like "vbetool dpms off" to that power management script to turn off the screen completely. On the other hand: the screen should be turned on when a key is pressed and console becomes actve again.
Is this possible?
