System Utilities

This chapter contains mainly hardware utilities. It also contains some applications used by other applications in the book for installation purposes.


Introduction to GPM

The GPM (General Purpose Mouse daemon) package contains a mouse server for the console and xterm. It not only provides cut and paste support generally, but its library component is used by various software such as Links 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!

User Notes:

Installation of GPM

Install GPM by running the following commands:

patch -Np1 -i ../gpm-1.20.1-segfault-1.patch &&
patch -Np1 -i ../gpm-1.20.1-silent-1.patch &&
./configure --prefix=/usr --sysconfdir=/etc &&
LDFLAGS="-lm" make

Now, as the root user:

make install &&
cp -v conf/gpm-root.conf /etc &&

Command Explanations

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

Configuring GPM

Boot Script

Install the /etc/rc.d/init.d/gpm init script included in the blfs-bootscripts-20060910 package.

make install-gpm

Config Files

/etc/gpm-root.conf and ~/.gpm-root: The default and individual user gpm-root configuration files.

/etc/sysconfig/mouse: This file contains the name of your mouse device and the protocol which it uses. To create this file, run the following as the root user:

cat > /etc/sysconfig/mouse << "EOF"
# Begin /etc/sysconfig/mouse

GPMOPTS="<additional options>"

# End /etc/sysconfig/mouse

Configuration Information

Examples of values to set MDEVICE, PROTOCOL, and GPMOPTS to are:


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