NAME

inputplug — XInput event monitor

SYNOPSIS

inputplug [-v] [-n] [-d] [-0] -c command-prefix

inputplug [-h|--help]

DESCRIPTION

inputplug is a daemon which connects to a running X server and monitors its XInput hierarchy change events. Such events arrive when a device is being attached or removed, enabled or disabled etc.

When a hierarchy change happens, inputplug parses the event notification structure, and calls the command specified by command-prefix. The command receives four arguments:

• command-prefix event-type device-id device-type device-name

Event type may be one of the following:

• XIMasterAdded
• XIMasterRemoved
• XISlaveAdded
• XISlaveRemoved
• XISlaveAttached
• XISlaveDetached
• XIDeviceEnabled
• XIDeviceDisabled

Device type may be any of those:

• XIMasterPointer
• XIMasterKeyboard
• XISlavePointer
• XISlaveKeyboard
• XIFloatingSlave

Device identifier is an integer. The device name may have embedded spaces.

OPTIONS

A summary of options is included below.

• -h, --help

  Show help (--help shows more details).

• -v

  Be a bit more verbose.

• -n

  Start up, monitor events, but don't actually run anything. With verbose more enabled, would print the actual command it'd run. This implies -d.

• -d

  Don't daemonise. Run in the foreground.

• -0

  On start, trigger added and enabled events for each plugged devices. A master device will trigger the "added" event while a slave device will trigger both the "added" and the "enabled" device.

• -c command-prefix

  Command prefix to run. Unfortunately, currently this is passed to execvp(3) directly, so spaces aren't allowed. This is subject to change in future.

• -p pidfile

  Write the process ID of the running daemon to the file pidfile

ENVIRONMENT

• DISPLAY

  X11 display to connect to.
