udev規則中的腳本不運行

我在筆記本電腦上運行Ubuntu 9.10（Karmic Koala），並希望NumLock自動切換，具體取決於我的USB鍵盤是否插入（numlock on）或拔下（numlock off）。udev規則中的腳本不運行

爲了達到這個目的，我首先安裝了「numlockx」包。 numlockx on和numlockx off工作正常。

掛鉤到設備系統，我想我會使用udev。我查看了StackOverflow上的其他問題，並閱讀了"Writing udev rules"。但是，我無法使udev規則正常工作。

首先，這裏的dmesg輸出的例子：我用udevadm info收集設備信息

因此，我創建了一個名爲/etc/udev/rules.d/usb-keyboard.rules文件：

ACTION=="add", ATTRS{manufacturer}=="Microsoft", SUBSYSTEM=="input", RUN+="/usr/bin/numlockx on" 

# Turn off NumLock when keyboard is unplugged. 
ACTION=="remove", ATTRS{manufacturer}=="Microsoft", SUBSYSTEM=="input", RUN+="/usr/bin/numlockx off"

我已使用udevadm test驗證規則是正確的：

的問題是，當鍵盤被插入或拔出時，NumLock鍵狀態不更改。我嘗試重新啓動udev服務，但沒有運氣。我的udev規則錯了嗎？我是否以這種錯誤的方式去做？

我不是這個很熟悉，但我的猜測是，鍵盤狀態由X11「管道」，它坐落在比udev的更高層次的管理，所以無論你做什麼下來越來越重要。您可以通過搜索/etc/X11中的配置文件來了解更多信息。
您可能會在superuser.com上獲得與此相關的更多相關答案（鏈接位於本頁底部）。我不會投票結束在這裏的問題，但其他人可能會。
