<title>Introduction to <application><acronym>GPM</acronym></application></title>

<para>The <application><acronym>GPM</acronym></application> (General
Purpose Mouse daemon) package contains a mouse server for the console
and <command>xterm</command>. It not only provides cut and paste support
generally, but its library component is used by various software such as
<application>Links</application> to provide mouse support to the
application. It is useful on desktops, especially if following
(Beyond) Linux From Scratch instructions; it's often much easier (and
less error prone) to cut and paste between two console windows than to
type everything by hand!</para>

<title>Installation of <application><acronym>GPM</acronym></application></title>

<para>Install <application><acronym>GPM</acronym></application> by running 
the following commands:
</para>

<screen><userinput><command>patch -Np1 -i ../gpm-&gpm-version;-segfault-1.patch &amp;&amp;
patch -Np1 -i ../gpm-&gpm-version;-silent-1.patch &amp;&amp;
LDFLAGS="-lm" ./configure --prefix=/usr --sysconfdir=/etc &amp;&amp;
make &amp;&amp;
make install &amp;&amp;
cp conf/gpm-root.conf /etc &amp;&amp;
ldconfig</command></userinput></screen>
</sect2>

<sect2>
<title>Command explanations</title>

<para><command>LDFLAGS="-lm"</command>: The math library 
must be linked with <command>gpm</command>, as ceil() is used in some cursor
scrolling logic.</para>

<!-- <para><command>ldconfig -n -l </command>: During installation, gpm outputs a
message to run the above command to create the proper library links.</para> -->

<para>Install the <filename>/etc/rc.d/init.d/gpm</filename>
init script included in the
<xref linkend="intro-important-bootscripts"/> package.</para>

<sect3><title>Config files</title>

<para><filename>/etc/gpm-root.conf</filename> and 
<filename>~/.gpm-root</filename>: The default and individual user 
<command>gpm-root</command> configuration files.</para>

<para><filename>/etc/sysconfig/mouse</filename>: 
This file contains the name of your mouse device and the protocol which
it uses.  To create this file, run the following:</para>

<screen><userinput><command>cat &gt; /etc/sysconfig/mouse &lt;&lt; "EOF"</command>
# Begin /etc/sysconfig/mouse

MDEVICE="<replaceable>[yourdevice]</replaceable>"
PROTOCOL="<replaceable>[yourprotocol]</replaceable>"
GPMOPTS="<replaceable>[additional options]</replaceable>"

# End /etc/sysconfig/mouse
<command>EOF</command></userinput></screen>
</sect3>

<sect3><title>Configuration Information</title>

<para>Examples of values to set <envar>MDEVICE</envar>,
<envar>PROTOCOL</envar>, and <envar>GPMOPTS</envar> to are:</para>

<screen><userinput>MDEVICE="/dev/psaux"
PROTOCOL="imps2"
GPMOPTS=""</userinput></screen>

<para>A list of which protocol values are known can be found by running
<command>gpm -t -help</command>.  The <envar>MDEVICE</envar> setting 
depends on which type of mouse you have.  For example,
<filename>/dev/ttyS0</filename> for a serial mouse (on Windows this is
COM1), <filename>/dev/input/mice</filename> is often used for
<acronym>USB</acronym> mice and <filename>/dev/psaux</filename> for PS2 
mice.  <envar>GPMOPTS</envar> is the 'catch all' for any 
additional options that are needed for your hardware.</para>
