Since my upgrade to Ubuntu 17.10 there's no option in the settings about what to do when the notebook-lid is closed any more.
Before this function had the options "do nothing" and "suspend" and maybe "shutdown".
The "do nothing" function did something: when the lid was closed, the display went dark and the screen was locked with the password.
My question is how to change the setting so that it's like I'm used to, so that the screen just locks but doesn't suspend when closing the lid.
