#StackBounty: #lock-screen Ubuntu 18.04 will not stop blanking screen

Bounty: 50

This was a problem in 17.10 and it’s carried over to 18.04 and at this point it’s driving me nuts.

My screen keeps blanking after one minute of idle. I cannot even read articles.

In Gnome settings, Privacy > Lock screen is off, and I’ve set Power > Blank Screen to Never and Automatic Suspend is set to Off

What else do I need to disable? I’ll decide when my screen is locked. I just want all of it off.

Update

Additional things I’ve checked and ruled out:

I’ve installed Dconf Editor and checked the settings there and I’m unable to find anything that changes the behaviour. I tried disabling the idle-dim setting under /org/gnome/settings-daemon/plugins/power and tried just disabling the entire power plugin, neither change has had an effect on the behaviour.

I’ve also combed through the nvidia-settings app and cannot find anything related to power or screen blanking there. My xorg server is using the out-of-the-box auto-detection for startup and there is no xorg.conf setting anything on my system. This is all just default 18.04 behaviour for me.

Found this question and checked the xset q output, adding it. You’ll note that my timeout and cycle settings are at 0 which was the solution there, however mine are already set to 0 and my screen is still blanking. That question is for Unity anyway and mine is for Gnome3
