syndaemon - a program that monitors keyboard activity and disables the touchpad when the keyboard is being used.
SYNTAX
syndaemon [-i idle-time] [-d] [-p pid-file] [-t] [-k] [-K]
DESCRIPTION
Disabling the touchpad while typing avoids unwanted movements of the pointer that could lead to giving focus to
the wrong window. This program needs SHMConfig "on" in your XOrg/XFree86 Synaptics Touchpad configuration.
OPTIONS
-i <idle-time>
How many seconds to wait after the last key press before enabling the touchpad. (default is 2.0s).
-d Start as a daemon, ie in the background.
-p <pid-file>
Create a pid file with the specified filename. A pid file will only be created if the program is started
in daemon mode.
-t Only disable tapping and scrolling, not mouse movements, in response to keyboard activity.
-k Ignore modifier keys when monitoring keyboard activity.
-K Like -k but also ignore Modifier+Key combos.
ENVIRONMENT VARIABLES
DISPLAY
Specifies the X server to contact.
CAVEATS
It doesn't make much sense to connect to a remote X server, because the daemon will then monitor the remote
server for keyboard activity, but will disable the touchpad on the local machine.
