I have the same question as this: How to stop screen going black after 10 min but with Ubuntu Mate 16.04, and an equivalent mate-power-manager-seetings does not exist. There is mate-power-statistics, mate-power-prefferences,mate-power-manager for options, but i have looked at these, and they are set in such a way that one would think the screen would never go blank, but still, every 10 minutes, the screen goes blank.

Ive looked at nummerous forum posts about how to stop screen blanking. some say edit /etc/kbd/config, others say edit xorg, or lightdm.conf. all, seem to only work sometimes. I want the solution that will work every time.

I am running a kiosk, and I need the screen to stay lit, and displaying, what can I do?

  • Have you looked in the screen saver preferences (`mate-screensaver-preferences`) in case a Blank screen saver has been set? – Sledge Hammer Aug 04 '16 at 12:32

You should try to find mate-power-manager.

If it doesn't exist, you can install it by opening a terminal and typing 

sudo apt install mate-power-manager

After installation, you can access it either via

  • Terminal: by typing mate-power-preferences
  • GUI: System > Control Center > Power Management and/or Screensaver (for your needs).

Install caffeine. It will solve your issue. To install, use this command 

sudo apt-get install caffeine

in a Terminal by summoning it with Ctrl-Alt-T
