<para>The system bell or beep is a feature of the X server, which
22
attempts to make good use of the available hardware. </para>
24
<para>&kde; normally does not use the system bell; instead using its
25
own system notifications, which could include log entries, message
26
popups, or its own beep. You can configure these in the
27
<guilabel>Manage Notifications</guilabel> &systemsettings; module.</para>
29
<note><para>It is not always possible for the X server to actually make
30
a beep sound with exactly the parameters selected due to hardware
31
limitations. For example, on most PCs, volume control is not very good
32
so the X server seems to fake low volume with a reduced duration of
33
the sound. Thus, if the settings do not seem to do anything, this is
34
because the X server and/or the hardware do not support anything
