Computer locks even when Screen Lock off

[John Rose]

Computer locks after a few minutes even when Automatic Screen Lock turned off. I've also tried Screen Lock after e.g. 30 minutes. This happens on both a new install of 18.04 (on this computer) or after an upgrade from 16.04 to 18.04 on another computer.

When you say "locks", does that mean you can unlock it with a password?

You're not talking about a permanent crash, right?

[John Rose (johnaaronrose)]

It's not a crash or a hang. It locks in terms of the screen being blank and the login password being required to unlock the screen. Also, I put this glitch down to the xorg package but I could be wrong.
