Screen going blank after a while

Question

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

Is there a file that I can configure/set the screen active constantly?
Where are these files located? (in the root? home?)
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 05 '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 05 '17 at 16:21

Open up /etc/lightdm/lightdm.conf using your favorite text editor.
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.
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 05 '17 at 13:27
@Bex I think he means to restart the process and/or service – Mohammad Ali Jan 08 '17 at 02:13
