To check your version:
$lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.5 LTS
Release: 20.04
Codename: focal#
To disable Ubuntu doing anything closing the laptop lid:
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:
HandleLidSwitch=ignore

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

or, from 15.04 onwards:
