<para>&cmd;<command></command> allows the management of displays in a dynamic
fashion. It is typically used in environments where it is not possible to list
the possible displays in the GDM configuration files. The
<command>&cmd;</command> command can be used to create a new display on a
particular display number, run all newly created displays, or remove a display.
The <command>&cmd;</command> can also be used to list all attached displays, or
only attached displays that match a pattern.</para>
<para>
This program is designed to manage multiple simultaneous requests and
works to avoid flooding the daemon with requests. If the socket connection
is busy, it will sleep and retry a certain number of times that can be tuned
with the <option>s</option> and <option>t</option> options.</para>

If the daemon socket is busy, <command>&cmd;</command> will sleep an amount of
time between retries. A random number of seconds 0-5 is added to the
<replaceable>int</replaceable> value to help ensure that multiple calls to
gdmdynamic do not all try to restart at the same time. A value of zero causes
the sleep time to be 1 second. Default value is 8 seconds.
