如何“锁定键盘”以防止在X11LinuxGnome上发送更多按键？

如何“锁定键盘”以防止在X11 / Linux / Gnome上发送更多按键？

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]+).*slaves+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 ;     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。
