只要使用xmodmap命令把坏的键的映射值和你想要替换的映射值互换一下就可以了，因为右方向键和End键离的最近，所以就用End键替换坏掉的右方向键。

首先查看右方向键和End键的值

# xmodmap -pke |grep -i end

keycode 87 = KP_End KP_1 KP_End KP_1

keycode 115 = End NoSymbol End

keycode 153 = XF86Send NoSymbol XF86Send

keycode 213 = XF86Suspend NoSymbol XF86Suspend

keycode 239 = XF86Send NoSymbol XF86Send

# xmodmap -pke |grep -i right

keycode 19 = 0 parenright 0 parenright

keycode 35 = bracketright braceright bracketright braceright

keycode 85 = KP_Right KP_6 KP_Right KP_6

keycode 114 = Right NoSymbol Right

keycode 188 = parenright NoSymbol parenright

keycode 232 = XF86MonBrightnessDown NoSymbol XF86MonBrightnessDown

keycode 233 = XF86MonBrightnessUp NoSymbol XF86MonBrightnessUp

keycode 237 = XF86KbdBrightnessDown NoSymbol XF86KbdBrightnessDown

keycode 238 = XF86KbdBrightnessUp NoSymbol XF86KbdBrightnessUp

这样就找出了End键 和 右方向键的值，但不是很确认 87 和 115 85 和 114 哪一个才是准确的，于是全都互换了在用户家目录下创建一个文件 .Xmodmaprc

keycode 85 = KP_End KP_1 KP_End KP_1

keycode 114 = End NoSymbol End

keycode 87 = KP_Right KP_6 KP_Right KP_6

keycode 115 = Right NoSymbol Right

保存退出：

执行 xmodmap ~/.Xmodmaprc

是更改生效

WOW～～，右方向键终于被复活了，不过得找一个替身哦
