使用xinput使用shell脚本可以很容易地做到这一点：

 #!/bin/sh

 do_it() {
     # need error checking there. We should also restrict which device gets
     # deactivated, by checking other properties.
     keyboard_ids="$(xinput list | sed -rn 's/.*id=([0-9]+).*slave\s+keyboard.*/\1/p')"

     for keyboard_id in $keyboard_ids; do
         # 121 is "Device Active".
         # use xinput watch-props $device_id to see some properties.
         xinput set-int-prop $keyboard_id 121 8 $1;
     done;
 }
 # you maybe don't want to exit in case of failure there.
 do_it 0 ; sleep 5; do_it 1

这种逻辑在Python中很容易重写。如果安装xinput是有问题的，那么最好获取xinput的源并尝试使用python-
xlib之类的库在Python中重新实现它。
