shell腳本如下：

#!/bin/bash
echo 'xinput list' 
xinput list

if [ ! -n "$1" ]; then
    echo "用法：./disnbkb.sh [id] [switch on/off]"
    echo "  [id] : 參考列表中 id=[id]"
    echo "  [switch on/off] : 1 = switch on, 0 = switch off"
else
    echo "指定筆記本鍵盤id="$1
    keyboardId=$1
fi

if [ ! -n "$2" ]; then
    iswitch=0
else
    iswitch=$2
    if [ $2 -eq 1 ]; then
        echo ":啟用"
    elif [ $2 -eq 0 ]; then
        echo ":禁用"    
    else
        echo ":未知"
    fi
fi

# 有參數(shù)才執(zhí)行，無(wú)參數(shù)只打印列表
if [ -n "$1" ]; then
    xinput set-prop $keyboardId "Device Enabled" $iswitch
fi

上述腳本保存為 didswitch.sh

以Ubuntu為例 ，在終端執(zhí)行 ./didswitch.sh，可打印出外設(shè)列表如下：

~$ ./didswitch.sh
xinput list

    ? AT Translated Set 2 keyboard              id=13   [slave  keyboard (3)]
用法：./disnbkb.sh [id] [switch on/off]
  [id] : 參考列表中 id=[id]
  [switch on/off] : 1 = switch on, 0 = switch off

要禁用筆記本自帶鍵盤，從上述列表找到 AT Translated Set 2 keyboard（不同筆記本名稱可能不同），對(duì)應(yīng)id=13

執(zhí)行 ./didswitch.sh 13 0

~$ ./didswitch.sh 13 0

    ? AT Translated Set 2 keyboard              id=13   [slave  keyboard (3)]
指定筆記本鍵盤id=13
:禁用

執(zhí)行后筆記本自帶的鍵盤就不可用了，外接鍵盤再執(zhí)行一次 ./didswitch.sh 13 1即可恢復(fù)使用。

注意：系統(tǒng)重啟禁用的鍵盤會(huì)恢復(fù)正常，如要永久禁用則需要設(shè)置開機(jī)自動(dòng)運(yùn)行。
