I have Ubuntu 16.04 installed with Unity (Ubuntu-Desktop).
As mentioned in several other threads, I have:
- Under Settings → Brightness & Lock set Turn screen off when inactive for to “never”.
- Under Settings → Power set Suspend when inactive for to “don’t suspend”.
- With
dconf-editor
in the directory/org/gnome/settings-daemon/plugins/power
uncheckedactive
. - With
dconf-editor
in the directory/org/gnome/desktop/screensaver
uncheckedidle-activation-enabled
(even though that seems deprecated in 16.04). - Run
gsettings set org.gnome.desktop.session idle-delay 0
- Run
gsettings set org.gnome.desktop.screensaver lock-enabled false
Still, Ubuntu keeps turning the screen off after 10 minutes (not locking it though). Any ideas on what to try?
Also, I have the same problem whether I decide to launch Unity or not. (When I'm in terminal only, not running LightDM, screen also goes black after 10 minutes.)

Your monitor is being turned off every 10 minutes because of the setting you have in:
The 600 seconds timeout is 10 minutes. You can disable this timeout by changing this setting to 0.
You can do this with:
I don't know what in your system is making this a default. But you can make this an automatic change by creating a script to change this and placing the script in your Startup Applications configuration:
Script to disable blanking:
Copy the script to
~/bin/
.Now set it to automatically run by typing
start applications
in the Ubuntu Search button and clicking Startup ApplicationsClick the option to Add, then browse to the script and add it.
