monitor on the right.</para>
|
|
|
|
<note><para>The preview monitor will often show the screen saver

larger than it is when the screen saver is activated. This is done on

purpose, since many of the details of the screen savers would be

<para>Each screen saver has a different set of setup options. By

<title>Removing and restoring a screen saver from your system</title>

<para>If you want to remove a screen saver from the list in this

Control Center Module, you will need to rename a file on your

|
system.</para>
|
|
|

<caution><para>Working as a <systemitem

<para>Be very careful following the next set of

<para>To delete a screen saver, type the following commands:</para>
|
|
|
|
<screen>
|
|
<prompt>bash$</prompt> <command>cd
|
|
$TDEDIR/share/applnk/System/ScreenSavers</command>
|
|
<prompt>bash$</prompt> <command>ls</command>
|
|
</screen>
|
|
|
|
<para>This will give you a list of files. You will notice
|
|
similarities between some of the file names and that of the screen saver you
|
|
want to remove. Simply rename the file of similarly named desktop
|
|
file to a name which does not end in
|
|
<emphasis>desktop</emphasis>.</para>
|
|
|
|
<para>Example:</para>
|
|
<screen>
|
|
<prompt>bash$</prompt> <command>cd
|
|
$TDEDIR/share/applnk/System/ScreenSavers</command>
|
|
<prompt>bash$</prompt> <command>mv KSpace.desktop KSpace.backup</command>
|
|
</screen>
|
|
|
|
<para>Will remove Space (GL) from the list</para>

|
|
<note><para>You must close the &kcontrolcenter; entirely and restart it before

the changes will be seen.</para></note>
|
|
|
|
<para>To restore the disabled screen saver, simply rename the file back to its
|
|
original name:</para>
|
|
|
|
<screen>
|
|
<prompt>bash$</prompt> <command>cd
|
|
$TDEDIR/share/applnk/System/ScreenSavers</command>

<prompt>bash$</prompt> <command>mv KSpace.backup KSpace.desktop</command>

<para>Restart the &kcontrolcenter;, and the screen saver is back in the

<sect2 id="grace">

<title>Advanced Settings: Grace period</title>

|
<para>There is a five second grace period after the screen saver
|
|
begins before a password is required even if <guilabel>Require
|
|
password</guilabel> is checked.</para>
|
|
<para>Locking the desktop manually, by clicking the lock icon

in the &kde; panel, causes the password protection to engage immediately with

no grace period.</para>
|

<para>To alter the grace period setting, you need to manually edit the
|
|
configuration file. To do so:</para>
|
|
<para>
|
|
<prompt>$</prompt> <command>cd <filename>~/.kde/share/config</filename>
|
|
</command>
|
|
</para>
|
|
<para>Now, using a text editor (the example uses &kate;, the &kde; text editor),
|
|
load the <filename>kdesktoprc</filename>.</para>

<para>
|
|
<prompt>$</prompt> <command>kate <filename>kdesktoprc</filename>

</command>

</para>
|
|
<para>Search through the file for the section labeled
|
|
<emphasis>[Screensaver]</emphasis>.</para>
|

<para>Look through all lines in the section for an entry entitled
|
|
<emphasis>LockGrace</emphasis>.</para>
|
|
<para>If the entry exists, you can edit the value of the entry. </para>
|
|
<screen>[Screensaver]
|
|
LockGrace=3000</screen>
|
|
<para>The value of the entity represents the duration of the grace period
|
|
in milliseconds. An entry of 3000, would change the grace period to 3 seconds.
|
|
You can set the value of the entry to any number between zero (no grace period)
|
|
and 300000 (5 minutes).
|
|
</para>
|
|
<para>If the entry does not exist, simply add the entry to the end of the
|
|
section.</para>
|
|
|
|
<para>Any changes to the configuration entry take effect
|
|
immediately.</para>
