I have a Ubuntu 14.04 set up as a kiosk that starts Firefox in /etc/init/x.conf like this:

exec su -c "startx /etc/X11/Xsession /home/kiosk/kiosk.sh --" kiosk

(see details here: How to make ubuntu 14.04 a kiosk)

I want the screen to stay on for 60 minutes before going blank, however I haven't been able to overrule the default 10 minutes limit.

This is what I have tried:

  • In lightdm screen blank options is set to 60 minutes for the kiosk user
  • I have tried to add an /home/kiosk/.xinitrc file with xset options
  • I have tried to add an XAUTHORITY=/home/kiosk/.Xauthority xset -display :0.0 s off in my kiosk start script
  • I have tried to add /etc/X11/xorg.conf with Option "BlankTime" "60"

What is the correct way to configure screen blank time when starting x with startx from a shell script?

Finally found a solution. The /etc/X11/xorg.conf is the right way to do it.

This is the xorg.conf that is working:

Section "ServerLayout"
    Identifier  "ServerLayout0"
    Option  "DPMS"      "false"
    Option  "BlankTime" "60"
    Option  "StandbyTime"   "0"
    Option  "SuspendTime"   "0"
    Option  "OffTime"   "0"
EndSection

Section "ServerFlags"
    Option  "BlankTime" "60"
    Option  "StandbyTime"   "0"
    Option  "SuspendTime"   "0"
    Option  "OffTime"   "0"
EndSection

It's not nessesary to have Blanktime in ServerFlags AND ServerLayout section, but I havn't had time to test which one is best.
