When using the Raspberry Pi 3 to run a presentation in Libre Office, the screen goes blank after a while. My questions:

  1. Is there a file that I can configure/set the screen active constantly?
  2. Where are these files located? (in the root? home?)
  3. Will the changes take effect without rebooting the Raspberry Pi?
  • The screen goes blank and what next? You press a key and the display is active again, or you need to reboot, or what? – techraf Jan 5 '17 at 12:40

  • @ppumkin given your follow up comment I understand what you were saying but the original comment did not come off that way. – Steve Robillard Jan 5 '17 at 16:21

  1. Open up /etc/lightdm/lightdm.conf using your favorite text editor.
  2. Look for the line #xserver-command=X. Change it to xserver-command=X -s 0 dpms
    • It should be at line 87 if things don't change.
  3. Save and reboot.

The simplest answer is to install gnome-system-tools - then you will have a menu, Preferences, Screensaver program that can help you do those settings in the GUI.

Run

sudo nano etc/kbd/config 

and try changing BLANK_TIME to 0 and POWERDOWN_TIME to 0.

Save the file and then restart the process by typing

sudo /etc/init.d/kbd restart
  • "restart the file"? What does that mean? – Bex Jan 5 '17 at 13:27
  • @Bex I think he means to restart the process and/or service – Mohammad Ali Jan 8 '17 at 2:13
