<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.
