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