Raspberry Pi Screensaver and Screen Blanking with Pidora

So I tried and failed to disable the screensaver and screen blanking within pidora on the Raspberry Pi. I was up against a time target and needed to find a solution.

I needed the screen to stay live, with no screen blanking or screensaver, even when the keyboard and mouse were completely disconnected. I tried a range of settings and all of them failed me within the time available. After aproxommatly 10 minuites, the screen would blank with either a black screen, gray screen, or screensaver depending on the settings in use.

I found some commands would work, however attempts to ensure this was the case after a reboot failed.

Option 1 – Disable the screensaver from within the settings menu

Option 2 – Reconfigure X power saving with .xinitrc

“You may need to install xset, a lightweight application that controls some X settings.”

apt-get install x11-xserver-utils

Now open up your ~/.xinitrc file (if you don’t have one then create it) and enter this:

xset s off         # don't activate screensaver
xset -dpms         # disable DPMS (Energy Star) features.
xset s noblank     # don't blank the video device

Start LXDE

exec /etc/alternatives/x-session-manager

To view your Xsession screen saver setting, use this command (must be used from xterminal)

xset q

Disable text terminals from blanking
change two settings in /etc/kbd/config

BLANK_TIME=0
POWERDOWN_TIME=0

Disable Xsession from blanking

Add these lines to /etc/xdg/lxsession/LXDE/autostart

@xset s noblank
@xset s off
@xset -dpms

Option 3: Simulate Input = The answer…
For me, the easiest answer in the end was to simulate mouse movement. A cop out some may say, but as this pi will never have a keyboard or mouse connected and I wanted the pointer out of the viewable area it also solved moving the pointer from the centre.

I created this file:

#!/bin/bash
# mousemove.sh - R. Jervis - Move the mouse to keep screen alive and force webpage refresh with F5. 

sleep 60

while :
do
	echo "Test"
	xdotool mousemove 30 45
	sleep 60
	xdotool mousemove 30 55
	sleep 60
	xdotool click 1
	xdotool key F5
done

I then enabled it to run on-boot.
