I'm a new Ubuntu 13.10 user. Closing the lid of my laptop does not result in the computer entering suspend mode, meaning each time I close my lid without manually suspending the computer the battery dies.

The proper settings are set in Power Management -- suspend the laptop on lid close for both AC and DC, but these do not have an effect on actual behavior.

It looks like this is a common problem for many users as far back as Ubuntu 11 -- the only solution I could find is the below. However, as a new linux user I'm not aware of how to actually execute the instructions. If someone could provide additional detail that would be tremendously helpful.

Thanks in advance.

/etc/acpi/events/lidbtn triggers /etc/acpi/lid.sh which triggers
 /etc/acpi/local/lid.sh.post at the end of the script.
 /etc/acpi/local/* allows you to add your own config (e.g. required for
 wmii).

 generate /etc/acpi/local/lid.sh.post
 make it executable and add:

 \#!/bin/bash
 grep -q closed /proc/acpi/button/lid/*/state
 if [ $? = 0 ]
 then
 /usr/sbin/pm-suspend
 fi

 wmii will now go to suspend mode when closing the lid. It'll
 automatically wake up when opening the lid.
    #!/bin/bash

    load=$(cat /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0A:00/power_supply/BAT0/capacity)
    min_load=20
    if [ $load <= min_load ]; then
        pm-suspend
    fi

(Note that # before a command indicates that it should be run by the superuser, so replace the # with sudo.)

Open logind.conf as root: # vim /etc/systemd/logind.conf and remove the # before HandleLidSwitch=suspend. You can also change the option suspend to hibernate or poweroff

Fix from Launchpad Bug #863834, comment #30:

  1. Open a terminal: Ctrl + Alt + t
  2. # mkdir /etc/acpi/local
  3. # vim /etc/acpi/local/lid.sh.post
  4. Copy this short script:

     #!/bin/bash
     if grep -q closed /proc/acpi/button/lid/*/state
     then
         /usr/sbin/pm-suspend
     fi
    

    ... and paste it into vim by typing: "+p

  5. Save by typing ZZ (in capitals)
  6. # chmod 755 /etc/acpi/local/lid.sh.post (so it works even when power management is handled under the logged-in user instead of root)

ps: if you are not sure how to use vim then replace it with gedit and sudo with gksu – Meow Dec 25 '13 at 3:41
    
Meow, thanks for the quick response. Unfortunately I'm still not 100% clear. Do I enter these commands in terminal? When I type 'sudo vim /etc/systemd/logind.conf', I get the error 'sudo: vim: command not found'. I'm also on a PC running linux, if that makes a difference. – Kyle Chadha Dec 25 '13 at 5:38
    
use sudo gedit /etc/systemd/logind.conf if vim is not installed & yes you need to enter them in the terminal – Meow Dec 25 '13 at 10:21
    
Hrm still does not work. No change on lid close after restart. '#HandlePowerKey=poweroff #HandleSuspendKey=suspend #HandleHibernateKey=hibernate HandleLidSwitch=suspend' – Kyle Chadha Dec 25 '13 at 16:40

This worked for me, but I had to add the following: sudo chmod 755 /etc/acpi/local/lid.sh.post – qbert220 Mar 23 '15 at 16:14

In response to this post, I have had the same problem with this on my Toshiba Satellite a305-s6902 (which I purchased solely to practice on Linux), and found that this worked for me:

sudo vim /etc/systemd/logind.conf

then as above, remove the # before HandleLidSwitch=suspend and save (ESC :wq).

HOWEVER ---> I find that I must put the computer into suspend manually FIRST, and after every reboot to engage the trigger. I do not know why, but this has worked consistently for me.

I've solve it by uncommenting variable LID_SLEEP=true from /etc/default/acpi-support.

For me the problem was that the lid close is handled different when an external monitor is connected. So changing that option as user in dconf-editor solved the problem for me:

Schema:

org.cinnamon.settings-daemon.plugins.power

or (depending on what desktop environment you use)

org.gnome.settings-daemon.plugins.power

Name:

lid-close-suspend-with-external-monitor

Set to:

true

Description:

With no external monitors plugged in, closing a laptop's lid will suspend the machine (as set by the lid-close-battery-action and lid-close-ac-action keys). By default, however, closing the lid when an external monitor is present will not suspend the machine, so that one can keep working on that monitor (e.g. for docking stations or media viewers). Set this key to False to keep the default behavior, or to True to suspend the laptop whenever the lid is closed and regardless of external monitors.
