How to prevent Ubuntu asking for password after laptop lid closed and reopened?

Question

I'm using Ubuntu 17.10 on a laptop and I disabled the 'screen lock', but every time I closed and reopened the laptop lid, the system shows me the GDM login and asks for password. Is there a way to prevent this?

Answer 1

This disables screen locking altogether, including when closing and opening the lid:

gsettings get org.gnome.desktop.lockdown disable-lock-screen # Get current setting, should be false
gsettings set org.gnome.desktop.lockdown disable-lock-screen 'true'
