I'm on the similar project and issue as OP with screen-blanking (HDMI output), running a Raspbian Server 2.4:

The standard user pi logs the session that auto-starts after a boot.

I have tried different approaches with no luck:


exec unclutter -root -noevents &
while sleep 5
        $HOME/websnurra-ng/websnurra-ng http://test.se

xset s off
xset s noexpose
xset -dpms
xset s noblank
setterm -blank 0 -powersave off -powerdown 0



# /etc/X11/xinit/xinitrc
# global xinitrc file, used by all X sessions started by xinit (startx)

# invoke global X session script
. /etc/X11/Xsession
xset s off
xset -dpms
xset s noblank
setterm -blank 0 -powersave off -powerdown 0


setterm -blank 0 -cursor off

I have run the xset commands manually in the terminal and they execute correct viewing xset q just as they do when I boot the configuration files, although the screen still blanks out after some minutes.

I wanted to execute them as root, to see if that would make a difference, but end up with an error message:

X11 connection rejected because of wrong authentication.
xset:  unable to open display "localhost:10.0"

I created a xorg.conf file with the following input and now it stays up:

Section "Monitor"
    Identifier "Monitor"
    Option "DPMS" "false"

Section "ServerLayout"
    Identifier "ServerLayout0"
    Option "BlankTime"  "0"
    Option "StandbyTime" "0"
    Option "SuspendTime" "0"
    Option "OffTime" "0"

What I did to disable screen blanking on my Raspberry Pi 2 with Raspbian.

Created a file on /etc/X11/Xsession.d/:

# /etc/X11/Xsession.d/98x11-screen_blank
xset s off
xset -dpms
xset s noblank

Be sure you have xset installed. The latest Raspbian already have it.


Just wanted to put this out there so others searching for this very issue (screen blanking) could find this answer useful.

In /etc/xdg/lxsession there are two directories (LXDE and LXDE-pi)

NOTE: This is if you are using the GUI (ex: in my case booting to terminal then using startx)

Many forums are saying to edit the autostart file in LXDE but that did not resolve my issue. What did is to edit the autostart in LXDE-pi with the below.

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
#@xscreensaver -no-splash

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

Then perform a reboot if needed.
The version currently using is:
Version: Raspbian GNU/Linux 7 \n \l

Hope someone finds this useful..
