GPM, short for General Purpose Mouse, is a daemon that provides mouse support for Linux virtual consoles.

Installation

Warning: xf86-input-synaptics is no longer actively updated. If possible, use libinput.

Install the gpm package. For touchpad support on a laptop you may also need to install xf86-input-synaptics.

Configuration

The -m parameter precedes the declaration of the mouse to be used. The -t parameter precedes the type of mouse. To get a list of available types for the -t option, run gpm with -t help.

# gpm -m /dev/input/mice -t help

The gpm package needs to be started with a few parameters. These parameters can be recorded by creating the file /etc/conf.d/gpm, or used when running gpm directly. As of 2016, the gpm.service file for systemd includes the parameters for a USB mice.

/usr/lib/systemd/system/gpm.service
ExecStart=/usr/bin/gpm -m /dev/input/mice -t imps2

Obviously, it should be edited, preferably in a systemd friendly manner, if there is another mice type, and the service is used.

  • For PS/2 mice, the parameters are:
-m /dev/psaux -t ps2
  • And IBM Trackpoints need:
-m /dev/input/mice -t ps2
Note: If the mouse has only 2 buttons, pass -2 to GPM_ARGS and second button will perform the paste function.

Once a suitable configuration has been found, start and enable the gpm.service.

For more information see gpm(8).
