Introduction to GPM

The GPM (general purpose mouse) daemon is a mouse server for applications running on the Linux console.

Project Homepage: http://unix.schottelius.org/gpm/

Dependencies

Note

The OPEN_MAX constant was removed in Linux 2.6.23. If your kernel version is 2.6.23 or greater, then you will need to apply the gpm-1.20.6-OPEN_MAX-1.patch which causes GPM to use the Sysconf variable _SC_OPEN_MAX instead.

Non-Multilib

If you kernel version is 2.6.23 or greater, apply the following patch:

patch -Np1 -i ../gpm-1.20.6-OPEN_MAX-1.patch

Compile the package:

patch -Np1 -i ../gpm-1.20.6-segfault-1.patch &&
patch -Np1 -i ../gpm-1.20.6-silent-1.patch &&
./configure --prefix=/usr --sysconfdir=/etc &&
LDFLAGS="-lm" make

Install the package

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

Command Explanations

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

Multilib

32Bit

If you kernel version is 2.6.23 or greater, apply the following patch:

patch -Np1 -i ../gpm-1.20.6-OPEN_MAX-1.patch

Compile the package:

patch -Np1 -i ../gpm-1.20.6-segfault-1.patch &&
patch -Np1 -i ../gpm-1.20.6-silent-1.patch &&
CC="gcc ${BUILD32}" ./configure --prefix=/usr --sysconfdir=/etc &&
LDFLAGS="-lm" make

Install the package

make install &&
ldconfig

N32

If you kernel version is 2.6.23 or greater, apply the following patch:

patch -Np1 -i ../gpm-1.20.6-OPEN_MAX-1.patch

Compile the package:

patch -Np1 -i ../gpm-1.20.6-segfault-1.patch &&
patch -Np1 -i ../gpm-1.20.6-silent-1.patch &&
CC="gcc ${BUILDN32}" ./configure --prefix=/usr \
    --sysconfdir=/etc --libdir=/usr/lib32 &&
LDFLAGS="-lm" make

Install the package

make install &&
ldconfig

64Bit

If you kernel version is 2.6.23 or greater, apply the following patch:

patch -Np1 -i ../gpm-1.20.6-OPEN_MAX-1.patch

Compile the package:

patch -Np1 -i ../gpm-1.20.6-segfault-1.patch &&
patch -Np1 -i ../gpm-1.20.6-silent-1.patch &&
CC="gcc ${BUILD64}" ./configure --prefix=/usr \
    --sysconfdir=/etc --libdir=/usr/lib64 &&
LDFLAGS="-lm" make

Install the package

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

Configuring

BootScript

Install the /etc/rc.d/init.d/gpm init script included in the bootscripts 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

MDEVICE="<yourdevice>"
PROTOCOL="<yourprotocol>"
GPMOPTS="<additional options>"

# End /etc/sysconfig/mouse
EOF

Configuration Information

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

MDEVICE="/dev/psaux"
PROTOCOL="imps2"
GPMOPTS=""

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.
