description

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

options

-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.

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.

environment variables

DISPLAY

Specifies the X server to contact.

exit codes

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.
