你會不會有這樣的經歷呢？當你正在敲代碼時，一不小心碰到觸摸板了，結果滑鼠亂飄。
使用syndaemon就可以免去你的煩惱了，syndaemon可以在你敲擊鍵盤后兩秒內屏蔽觸摸板，以下是syndaemon的manual:
Name
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
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
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.

將syndaemon放入/etc/X11/xinit/xinitrc-common里就可以了。
