I'm using Ubuntu 18.04 and would like to disable the lock screen. I have followed instructions to the change the turn off the Screen Lock
option under Settings -> Privacy > Screen Lock
(as so:)
but after a few minutes of idle time I am presented with a screen where I need to press enter to get my desktop back.
Usually I wouldn't be so lazy and would just press the enter button but I've noticed some other problem with Ubuntu 18.04 in that on occasion, after the screen locks, the desktop 'breaks' by presenting me with a purple, fuzzy and unresponsive desktop. My hope is that if I disable the locking behaviour I'll also stop the other problem.
It's Under
Power
Settings, calledPower Saving
->Blank Screen
