Ubuntu - Power management

To make Ubuntu do nothing when laptop lid is closed:

From For 13.10 onwards:

Open the /etc/systemd/logind.conf file in a text editor as root, for example,

sudo -H gedit /etc/systemd/logind.conf

If HandleLidSwitch is not set to ignore then change it:


Other settings that the action can be ignored: HandleLidSwitchExternalPower, HandleLidSwitchDocked, IdleAction.

Restart the systemd daemon (be aware that this will log you off) with this command:

sudo systemctl restart systemd-logind

or, from 15.04 onwards:

sudo service systemd-logind restart
