Problem with xset dpms force off

[sehyoun]

This will have the problem that the monitor turns on after a few seconds, as described in El Raspa's original post.

Oh, I see... It actually just lengthened the time before the monitor turning back on (2sec -> 1 min). Sorry about that. I guess I should have waited longer than 30 secs to be sure.

Ok. Apparently how you call on the screensaver might matter. Could you test

gnome-screensaver-command -a && xset dpms force off

I tested it twice up to 5 minutes and once up to 20 minutes this time. I hope it didn't just lengthen the wait time again since 20 mins is about at the edge of my patience =P

The weird thing is that a simple command like:

#!/bin/bash
sleep 2
xset dpms force off

does the trick...

I am trying to make a gnome-screensaver module based on that script. I just needs some good documentation on how to make .desktop modules. Anyone?

Using Google get's me nowhere

Same problem here. Something is defeating the screen auto-shut off... like sending mouse or keyboard events to the system. This is a worldwide energy disaster with millions of screens lit up when they should be off! How may megawatts of wasted energy is that?!

Never mind scripts and workarounds... this thread is old, so why haven't the devs fixed this????

My solution lcdonoff script - simple and elegant

#/bin/sh
OID='LVDS1'
STATE=`xrandr | grep $OID | grep -c "ted ("`
case $STATE in
'1')
xrandr --output $OID --auto
;;
'0')
xrandr --output $OID --off
;;
esac

replace OID by your device

...and the best is - you can still control your music player, while your LCD is turned off

That works, but only if you have that script set on a button, not an icon. Though, I have only tested it on a laptop, so I do not know if it works on a desktop. I'm sure it can be adapted, though. Of course, you can usually turn those monitors off.

Nxmehta's script still is my choice, and hasn't failed me for several Ubuntu versions, including Natty.

A little bit of a thread revival (1 month ~), but I wanted to thank nxmehta for his script and also pass a little info on for those who might want screenlock at the same time.

I KNOW there is a more elegant way, so when one of you guys read this and think of that better way, be sure to post and make me feel stupid

I created one script (simply called 'lock') that contained:

#!/bin/bash
xflock4 &
sleep 3
python /home/user/scripts/screenlock

and then pasted nxmehta's python script into another script at that location. I then bound a key combination to execute 'lock', which enables screen lock and follows by executing nxmehta's script to turn off (and keep off!) the monitor.

I did it this way in hopes I can use his script to figure out how to get the screensaver itself to shut off the monitor ( )

Thanks again..

Wow, it's been almost exactly 1 year since I posted that python script... and the bug still isn't fixed in Ubuntu. Glad that some people are getting use out of it though I guess.

I'll check in around June 2012... here's hoping that people don't have to keep using a python script to turn their screen off!

Haha, I hope so too. Regardless, I'm sure I speak for all of us on here: thanks for the script.

Running Gnome 3 on Arch with the same issue but I can't get the script to work, I get this error:

File "./monitoroff.sh", line 21
    print display.next_event()
                ^
SyntaxError: invalid syntax

I've switched to xfce4-power-manager which doesn't integrate in the Gnome 3 top bar, but I'll make do for the meantime.

It's a shame gnome-power-manager as yet to fix this conflict with xset dpms force off.
