syndaemon1
A program that monitors keyboard activity and disables the touchpad when the keyboard is being used.
Usage
syndaemon [-i
idle-time]
[-m
poll-inverval]
[-d]
[-p
pid-file]
[-t]
[-k]
[-K]
[-R]
Overview
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.
-
-? -
Show the help message.
Environment
Exit status
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.
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.
