How to setup ubuntu to not shutdown when closing the lid, while connected to an external monitor

linux setup configs

How to do it

• When connecting an laptop to an monitor and if you want to only show display on the external monitor, you tend to close the laptop lid.
• By default, ubuntu shutsdown the system / goes into hibernation mode.
• This can be avoided by changing a config in /etc/UPower/UPower.conf.
• open in your favourite text editor, since its a system file, you need an root access say sudo vim /etc/UPower/UPower.conf
• search for IgnoreLid and make it to true like: IgnoreLid=True and save it
• reload the power service by, sudo service upower restart
