how to wake up sleeping monitor using batch script/command

[Antonio Olivares]

Dear folks,

I have a Flat Panel Monitor with built in speakers. If the monitor is on(not sleeping), the speakers work. When the Monitor goes to sleep, the speakers no longer work :(, I have a cron job that plays music in the morning, but since the monitor is sleeping the music does not play :(

I tried adding a command to wake up the monitor like
48 04 * * 1-5 sleep 2; xset dpms force on > /dev/null 2&>1

but the monitor does not wake up :(, I tried using variations like
xset -dpms

and

xset +dpms

and force on, force off to no avail. I sent a message to list, on how the crontab job was set and the script itself, but it has not made it to list, or was deleted? If you get a double post, please accept my apologies in advance, don't know how to blame, users* list or yahoo mail^{1}.

Regards,


Antonio

{1} yes poc and others, yahoo mail sucks, but being on it for a great while makes it hard to be apart from it :(, I go back to classic profile when using linux, since on windblows, the new yahoo mail does not do a good job of quoting and throws message replies to /dev/null in many cases, and threading sucks like Rahul says :)

Install the xdotool package (available on F11...not sure if F14 has it)
and then use one of the commands to move the mouse.

On my notebook it works, but it takes 1 min plus.

Thanks for helping Ed & JB.

Some observations when done on a command line.
- the screen does not come up when
$ xset dpms force off ; sleep 10 ; xset dpms force on > /dev/null 2&>1
- the screen DOES come up after 10s when
$ xset dpms force off ; sleep 10 ; xset dpms force on

Neither of these incantations will turn my screen on....

xset dpms force off ; sleep 10 ; xdotool mousemove_relative 1 1

works fine...

There is a possibility that BIOS / monitor / APM settings make a difference.

Which would not be a problem with xdotool and which is why I feel that
would be the preferred "universal" solution.

You know I say "Doc it hurts when I do this."
My doctor says "Don't do that."

It looks like the redirects are causing the command to not work
properly, so don't use them.

Now the hard part may be to send Antonio to that doctor :-)

Nah, just send the monitor.

BTW, it is quite interesting what does work and what does not. Should
prove interesting once I get Linux installing on that creaking ancient
machine.

works from cli, but does not when called from the script :(,

@James & JB
the redirection > /dev/null 2>&1

is to avoid having shitloads of mail by th mailer :)
Will report back if I can get it to work, otherwise I will have to get Ed's solution.

Thanks for helping out.

I did finally fire up my F14 system and verified that xdotool is
available with F14.

Yep. However, does this work on the command line as well? It looked
like it did not on JBs machine.

Another FYI....

If you run this from a cron job you'll need to add "export DISPLAY=:0".

Will try to put into script. Do I put it before xset dpms force on; command or after? in case it is important.

needs to go before all other display related commands as it sets the
environment variable needed by all the commands related to the DISPLAY.

Yes, it is case sensitive.

Awesome!!!

with export DISPLAY=:0, the screen wakes up & plays the music :)

#!/bin/sh

export DISPLAY=:0
/usr/bin/xset dpms force on;
/usr/bin/xterm -display :0 -bg white \
-e /usr/bin/mplayer --really-quiet -shuffle -playlist ~/.playlist -stop-xscreensaver & PID=$! > /dev/null 2>&1
sleep 1800
kill $PID
/usr/bin/xset +dpms

Thanks, Ed, JB, & James, could not have done it without your help!
Happy Holidays to all;

Antonio

This is rather strange and unnecessary. mplayer is perfectly capable of
playing audio without an xterm. You can replace all the xterm stuff by just,

/usr/bin/mplayer --really-quiet -shuffle -playlist ~/.playlist
-stop-xscreensaver

Go back and read the OP's email. His speakers are built in to his flat
panel display. What is happening is the speakers are being powered off
when the display is powered off by DPMS (Energy Star). Hence the need
to "wake it up".

Yes, that was not the problem :(, the problem was for the monitor to wake up and play the music (monitor with built in speakers); still I like to have xterm to change songs, or o q(quit) faster :)
