Running: Xubuntu 14.04 32-bit.

I have read several outdated, not working, working different that I want answers here and elsewhere. I had a script that resulted in shutting my Laptop down at boot time after I set it to autostart.

I also tried it install complexshutdown despite that tool having died in 2011 and has a bug on Lauchpad that his exact option is not available. It not even installed on 14.04 here.

I am looking for a simple straightforward script that is actually tested and working that I can put into the autostart that is doing nothing but checking for activity (mouse/keyboard) and shutting down my laptop if there was none for 2 hours.

Thanks.

This is probably the best solution. No need for screensaver tweaking and running.

Install sudo apt-get install xprintidle

Put this script into autostart:

#!/bin/bash

idletime=$((1000*60*60*2)) # 2 hours in milliseconds

while true; do
    idle=`xprintidle`
    echo $idle
    if (( $idle > $idletime )); then
        #sudo shutdown -P now
        dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 "org.freedesktop.login1.Manager.PowerOff" boolean:true
    fi
    sleep 1
done

The comments and @Jobin 's answer did lead me to investigate myself again and I actually found a unfinished script with xprinttime but without any loop in the script. Probably not finished this because my linux/bash knowlege was not good at the time. I also did put the script I had in rc.local or something like that triggered the shutdown on boot. Thanks to @Jobin for the reminder how to add startup apps in XFCE, I already knew this but ... and credits for the dbus thing, never saw that, better then shutdown since it not requires root.

This is an old question but I thought I would answer it with what works for me in Ubuntu 21.04. You can set an IdleAction in your systemd/logind.conf file.

Edit the file using:

sudo nano /etc/systemd/logind.conf

and add:

IdleAction=poweroff
IdleActionSec=120min

I have tested it with IdleActionSec=1min and the machine shuts down as expected.

After having looked at a number of options for shutting down after a certain time of inactivity, it seems that xautolock is the easiest way. All credits to Sparhawk for mentioning about xautolock.

Thanks to Sneetsher for pointing out to xscreensaver. Using xscreensaver, I could manually specify what to do after a certain amount of time of inactivity. To use xscreensaver, you need to install it using:

sudo apt-get install xscreensaver

or install it from the software center and then run it once using:

xscreensaver-demo

or type "xscreensaver" on the dash and open "Screensaver".

This will create a ~/.xscreensaver file. Open it and search for the line:

programs:                                                                     \

and add:

dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 "org.freedesktop.login1.Manager.PowerOff" boolean:true \n\

just below the

programs:                                                                     \

line.

You can specify the time after which shutdown should be triggered by changing the line starting with timout. Modify it to

timeout:        2:00:00

to shutdown after two hours.

Have a look at my .xscreensaver file here.

This should poweroff your machine after two hours of inactivity or whatever time you specify in the script.

Notes:

  • Have a look at this question to see how to add xscreensaver on boot.

  • I tried using complex shutdown, but the bug here seems to affect me so could not happen. Otherwise, a graphical application would have been available for this.

  • This could be achieved using xautolock, however, as redanimalwar pointed, out a timout greater than 1 hour is not possible without modifying its source code and recompiling.

This is my simplified script, this requires that you install the "xprintidle" package and modify the shutdown command so that is possible to run without sudo/password.

sudo chmod u+s /sbin/shutdown
sudo apt-get install xprintidle

Script

#!/bin/bash
idletime=$((15*60*1000)) # 15 min in milliseconds
idle=0

while [ $idle -lt $idletime ];do
    idle=`xprintidle`
    sleep 1
done
shutdown -P now

Modified @redanimalwar script to warn user and give a chance to cancel the shutdown. For tests, it is using 3 seconds and a simple message. Please adjust for your tastes. HTH.
