syndaemon - a program that monitors keyboard activity and disables the touchpad when the keyboard is being used.


syndaemon [-i idle-time] [-m poll-inverval] [-d] [-p pid-file] [-t] [-k] [-K] [-R]


Disabling the touchpad while typing avoids unwanted movements of the pointer that could lead to giving focus to the wrong window.


-i <idle-time> How many seconds to wait after the last key press before enabling the touchpad. (default is 2.0s). -m <poll-interval> How many milliseconds to wait between two polling intervals. If this value is too low, it will cause unnecessary wake-ups. If this value is too high, some key presses (press and release happen between two intervals) may not be noticed. This switch has no effect when running with -R. Default is 200ms. -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. -R Use the XRecord extension for detecting keyboard activity instead of polling the keyboard state. -? Show the help message.


DISPLAY Specifies the X server to contact.


If syndaemon exists with a return code other than 0, the error encountered is as below. Exit code 1 Invalid commandline argument. Exit code 2 The connection to the X sever could not be established or no touchpad device could be found. Exit code 3 The fork into daemon mode failed or the pid file could not be created. Exit code 4 XRECORD requested but not available or usable on the server.


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.
