I am working on a project similar to the one at http://www.instructables.com/id/Raspberry-Pi-Wall-Mounted-Google-Calendar/?ALLSTEPS

Similarly, I need my pi to stay on constantly. I have the regular Raspbian OS installed and I am using Iceweasel browser to run a web application all day.

I have tried every single one of these suggestions from this link http://www.bitpi.co/2015/02/14/prevent-raspberry-pi-from-sleeping/

Yet the pi fails to stay on longer than 10 minutes. Any help would be greatly appreciated.

  • Just as a side-comment - I picked up an Azpen A745 android tablet last weekend for $30 bucks at Microcenter - and it has a Google Calendar. In a few easy steps you can disable screen dimming/sleep in Android and you have a wallmounted Google Calendar solution :) Display viewing angle is not fantastic, but this saves you a lot of work - unless you are of course committed to using the rPi for this :). I use mine as a terminal for RuneAudio - I velcroed it to the wall. – Phil B. Jun 22 '15 at 17:47
  • Thanks @PhilB. but I am not running Google Calendar. Im running a web application I built and also its on 40 inch screen. But thank you for introducing me to RuneAudio ! Can't wait to try that out – Javed Ali Jun 22 '15 at 19:12
  • Thanks @Huygens I tried that one as well. I completely reinstalled the OS and the solution below worked – Javed Ali Jun 24 '15 at 13:36
  • You can always install gnome-utils and gain control over the screensaver via the preferences menu. Screen banking is easy to control there. – SDsolar Jan 10 '17 at 14:36

I don't know why it's not working since the last option mentioned in that post (lightdm configuration - Xsession blanking) worked pretty good for me.

Here is the easiest way for you.

Install xscreensaver by "sudo apt-get install xscreensaver"

Once installed, go to Rpi's desktop "Menu" (left top corner) [I'm assuming that you're running a raspbian?]

Go to preference ---> screensaver.

You will see a screen saver main menu. In mode : section, select "disable screensaver" and close.

Reboot Rpi. It should work now.

Also have a look at links below:

Disable screen blanking in X-Windows on Raspbian

How do I prevent the screen from going blank?

Hope it helps.
