syndaemon - a program that monitors keyboard activity and disables the touchpad when the keyboard is
Contents
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.
Description
Disabling the touchpad while typing avoids unwanted movements of the pointer that could lead to giving
focus to the wrong window.
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.
Exitcode1
Invalid commandline argument.
Exitcode2
The connection to the X sever could not be established or no touchpad device could be found.
Exitcode3
The fork into daemon mode failed or the pid file could not be created.
Exitcode4
XRECORD requested but not available or usable on the server.
Name
syndaemon - a program that monitors keyboard activity and disables the touchpad when the keyboard is
being used.
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.
