Turn off monitor via CLI ??
 

Hello all --

Seems like just about anything is possible on Linux so I will try my luck at this one...

I would like to run a command that disables the monitor temporarily during the boot process. Then enable it again once a program has started. I am think of adding it to the rc.local as I believe it is read early in the boot process (don't quote me on that though).

I know how to check if a the program is started but I have no idea how to disable/enable the monitor.

Has anyone tried to do this before?

Thank you.

monitor
 

well I used to push the power button on mine.It was blank then come back and push the button agian. good luck.

I think I have the power button under control... ;)


Any suggestions are appreciated.

Thanks.

Since you can setup power management in the GUI, one would assume that there is a command somewhere.

The first thing to try is a Google search.
The second might be the X-Windows docs.

The last resort might be to change your power management setup and then search to see what files were changed.

I think it's something like 'xset dpms force off'.

Well, I'll be darned.....

I just did "xset dpms force standby" and it worked.

Just for kicks where are commands like xset documented (other than the man pages)?

Thank you for the tip!

My monitor does not turn off when I type it in?
I must be missing an application since it works for others.

I installed x11 / gnome after the initial install.

apt-get -y --force-yes install xserver-xorg-core xfonts-base gnome-desktop-environment

I'm not aware of any documentation for xset other than the manpages.

jchambers, what happens when you run the xset command?

I have a button on my gnome toolbar I setup to turn off the monitor for night time since my computer is in my bedroom (yes, I could just hit the power button, but this allows me to wake it up with just a mouse movement)

Nothing really, it accepts the command without any errors but nothing happens.

I tried various commands with xset and used xset q to view them with no results. Not sure where to go from here.

One more question.
Is there a command I can use from the terminal (beofre X starts) to turn off the monitor.
