<title>Dim the Monitor When Idle</title>
<p>
When your laptop computer is running on battery, the screen will dim when the computer is idle in order to save power.
</p>
<p>
You can adjust the dimming brightness, disable it, or change the amount of time before dimming by following these steps:</p>
<steps>
<item><p>Click <keyseq><key>Alt</key><key>F2</key></keyseq></p></item>
<item><p>Type <input>gconf-editor</input>. The <app>Gnome Configuration Editor</app> window opens.</p></item>
<item><p>In the left panel click <guiseq><gui>/</gui><gui>apps</gui><gui>gnome-power-manager</gui><gui>backlight</gui></guiseq>.</p></item>
<item><p>In the right panel, you can now adjust the <gui>brightness_dim_batter</gui>, <gui>idle_brightness</gui>, and <gui>idle_dim_time</gui> by clicking twice (not double-clicking) on the associated <gui>Value</gui>. This will allow you to change the value in the field. </p></item>
<item><p>You can also choose to disable this feature by unchecking the box next to <gui>enable</gui>.</p></item>
</steps>

<p>Explain that screen dimming is a power saving feature, normally when disconnected from AC power. Link to power-dim to explain how to control this behaviour.</p>
