如何使用 xset 点亮 Caps Lock 指示灯？
我编写了一个小 fetchmail 脚本，用于检查远程服务器并在收到新邮件时播放音频文件。我还想在邮件可用时点亮我的键盘灯之一，但我遇到了问题。我可以用这个点亮滚动锁定灯：
/usr/bin/xset led named "Scroll Lock"
但我不能以同样的方式点亮大写锁定：
/usr/bin/xset led named "Caps Lock"
我尝试用数字（1-6）指定按键，但尽管更改了神秘的“LED面罩” （用“xset q”可见）我没有看到灯光有任何变化。
这是因为我将 Caps Lock 键映射为另一个 Ctrl 键而损坏了吗？
在 ~/.Xmodmap 中，我得到：
keycode 66 = Control_L
clear Lock
add Control = Control_L
我不想切换大写锁定，只想切换灯光。有办法做到这一点吗？
进一步说明
这是在 x86 kubuntu lucid 机器上，但我稍后会迁移到 debian。我在 python 守护进程中以非特权用户身份运行该脚本。以 root 身份运行相同的脚本将不起作用，因为 fetchmail 是为我自己配置为用户的。最后，这一切都在 tmux 会话中运行。
当我开始这个过程时，我读到了有关 setleds 的信息，但它似乎仅限于非 x 会话中的终端。
以 root 身份登录并运行 'setleds -D +caps < /dev/tty7' 可以工作，但运行 'sudo setleds -D +caps < /dev/tty7' 给我一个权限被拒绝的错误。
xset 命令似乎非常适合我的应用程序，它只是拒绝更改 Caps Lock 指示灯。
I wrote a little fetchmail script that checks the remote server and plays an audio file when I have new mail. I also wanted to also light up one of my keyboard lights when the mail was available but I ran into a problem. I am able to light up the scroll lock light with this:
/usr/bin/xset led named "Scroll Lock"
But I can't light up the Caps Lock in the same way:
/usr/bin/xset led named "Caps Lock"
I tried specifying the key with a number (1-6) but despite changing the mysterious 'LED mask' (visible with 'xset q') I saw no change to the lights.
Is this broken because I've mapped my Caps Lock key as another Ctrl?
In ~/.Xmodmap I've got:
keycode 66 = Control_L
clear Lock
add Control = Control_L
I don't want to toggle caps lock, just the light. Is there a way to do this?
Further Explanation
This is on a x86 kubuntu lucid machine but I will migrate to debian later. I'm running the script as a unprivileged user in a python daemon. Running the same script as root won't work because fetchmail is configured for myself as a user. And finally, this is all run in a tmux session.
When I began this process I read about setleds but it seems to be restricted to terminals in non x sessions.
Logging in as root and running 'setleds -D +caps < /dev/tty7' works but running 'sudo setleds -D +caps < /dev/tty7' gives me a permission denied error.
The xset command seems perfect for my application, it just refuses to change the Caps Lock light.

root下执行：
setleds -D +capssetleds -D +capssetleds -D +capssetleds -D +caps/dev/console很黑客，但对我有用:)
Execute under root:
setleds -D +caps < /dev/consoleHackish, but works for me :)
