[ale] linux screen saver

[Jim Kinney]

Hi John,

I have Fedora 10 which runs gnome 2.24. The gdm greeter screen has a
blanker built in. It is controlled by global gconf settings. Those
settings are found in /etc/gconf/schema/gnome-screensaver.schemas

Every language supported by gnome is in those files so it hard to dig
through. The setting that does the timing is:

    <schema>
      <key>/schemas/apps/gnome-screensaver/idle_delay</key>
      <applyto>/apps/gnome-screensaver/idle_delay</applyto>
      <owner>gnome-screensaver</owner>
      <type>int</type>
      <default>10</default>
      <locale name="C">
        <short>Time before session is considered idle</short>
        <long>
          The number of minutes of inactivity before the
          session is considered idle.
        </long>
      </locale>

Also need:
<gconfschemafile>
  <schemalist>
<schema>
      <key>/schemas/apps/gnome-screensaver/idle_activation_enabled</key>
      <applyto>/apps/gnome-screensaver/idle_activation_enabled</applyto>
      <owner>gnome-screensaver</owner>
      <type>bool</type>
      <default>TRUE</default>
      <locale name="C">
        <short>Activate when idle</short>
        <long>
          Set this to TRUE to activate the screensaver
          when the session is idle.
        </long>
      </locale>
<schema>
      <key>/schemas/apps/gnome-screensaver/mode</key>
      <applyto>/apps/gnome-screensaver/mode</applyto>
      <owner>gnome-screensaver</owner>
      <type>string</type>
      <default>single</default>
      <locale name="C">
        <short>Screensaver theme selection mode</short>
        <long>
          The selection mode used by screensaver.  May be "blank-only"
          to enable the screensaver without using any theme on activation,
          "single" to enable screensaver using only one theme on activation
          (specified in "themes" key), and "random" to enable the
          screensaver using a random theme on activation.
        </long>
      </locale>

 <schema>
      <key>/schemas/apps/gnome-screensaver/themes</key>
      <applyto>/apps/gnome-screensaver/themes</applyto>
      <owner>gnome-screensaver</owner>
      <type>list</type>
      <list_type>string</list_type>
      <default>[blank-only]</default>
      <locale name="C">
        <short>Screensaver themes</short>
        <long>
          This key specifies the list of themes to be used by the
          screensaver. It's ignored when "mode" key is
          "blank-only", should provide the theme name when "mode" is
          "single", and should provide a list of themes when "mode" is
          "random".
        </long>
      </locale>

  </schemalist>
</gconfschemafile>
