Display does not dim when idle

[chreko]

My screen does not dim when idle. I have modified the settings in org.gnome.settings-daemon.plugins.power as follow:

org.gnome.settings-daemon.plugins.power active true
org.gnome.settings-daemon.plugins.power button-hibernate 'hibernate'
org.gnome.settings-daemon.plugins.power button-power 'interactive'
org.gnome.settings-daemon.plugins.power button-sleep 'suspend'
org.gnome.settings-daemon.plugins.power button-suspend 'suspend'
org.gnome.settings-daemon.plugins.power critical-battery-action 'suspend'
org.gnome.settings-daemon.plugins.power idle-brightness 1
org.gnome.settings-daemon.plugins.power idle-dim-ac true
org.gnome.settings-daemon.plugins.power idle-dim-battery true
org.gnome.settings-daemon.plugins.power idle-dim-time 5
org.gnome.settings-daemon.plugins.power lid-close-ac-action 'suspend'
org.gnome.settings-daemon.plugins.power lid-close-battery-action 'suspend'
org.gnome.settings-daemon.plugins.power lid-close-suspend-with-external-monitor false
org.gnome.settings-daemon.plugins.power notify-perhaps-recall true
org.gnome.settings-daemon.plugins.power percentage-action 2
org.gnome.settings-daemon.plugins.power percentage-critical 3
org.gnome.settings-daemon.plugins.power percentage-low 10
org.gnome.settings-daemon.plugins.power priority 1
org.gnome.settings-daemon.plugins.power sleep-display-ac 600
org.gnome.settings-daemon.plugins.power sleep-display-battery 600
org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 0
org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'suspend'
org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 0
org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type 'suspend'
org.gnome.settings-daemon.plugins.power time-action 120
org.gnome.settings-daemon.plugins.power time-critical 300
org.gnome.settings-daemon.plugins.power time-low 1200
org.gnome.settings-daemon.plugins.power use-time-for-policy true

Please note that:
1.) I can modify brightness through: echo 5 > /sys/class/backlight/acpi_video0/brightness
2.) The default value for org.gnome.settings-daemon.plugins.power idle-brightness is 30

I am using a notebook HP envy 14 with:
Ubuntu 13.04 AMD64

Hi,
as this bug is a bit old and 13.04 is already reached EOL
are you still affected by this?

My laptop will dim after idle for about 30 seconds when running on battery (or set idle-dim-ac to true, it will also dim on AC after about 30 seconds)
