# LS-WVL Debian 安裝後選項

##### **Triggerhappy 按鈕**

```
apt install triggerhappy
```

**監聽按鈕**

```
thd --dump /dev/input/event*   
```

**建立關機功能**

```
echo "SW_LID 0 poweroff" > /etc/triggerhappy/triggers.d/gpf.conf
```

**修改`/lib/systemd/system/triggerhappy.service`，把ExecStart user的nobody改成root，不然無權限執行poweroff**

```
ExecStart=/usr/sbin/thd --triggers /etc/triggerhappy/triggers.d/ --socket /run/thd.socket --user root --deviceglob /dev/input/event*
```

**重啟加載配置**

```
systemctl daemon-reload
systemctl restart triggerhappy
```

**即可按鈕實現關機**

##### **風扇控制**

**風扇狀態`/sys/class/thermal/cooling_device0/cur_state`**

**CPU溫度`/sys/class/thermal/thermal_zone0/temp`**

**安裝`smartmontools`**

```
apt install smartmontools
```

**硬碟溫度`/usr/sbin/smartctl -a -d ata /dev/sda | grep -m 1 Temperature | awk '{print $10}'`**

**風扇自動化腳本**

```
#!/bin/bash
timestamp=$(date "+%Y-%m-%d %H:%M:%S")
# CPU溫度
cpu_temp=$(< /sys/class/thermal/thermal_zone0/temp)
cpu_temp=$(( cpu_temp / 1000 ))

# 硬碟溫度
hdd_temp=$(/usr/sbin/smartctl -a -d ata /dev/sda | grep -m 1 Temperature | awk '{print $10}')

echo "[$timestamp] CPU Temperature: ${cpu_temp}C"
echo "[$timestamp] HDD Temperature: ${hdd_temp}C"

# cpu偵測
if [ "$cpu_temp" -gt 60 ]; then
    echo 0 > /sys/class/thermal/cooling_device0/cur_state
elif [ "$cpu_temp" -gt 55 ]; then
    echo 1 > /sys/class/thermal/cooling_device0/cur_state
elif [ "$cpu_temp" -gt 50 ]; then
    echo 2 > /sys/class/thermal/cooling_device0/cur_state
elif [ "$cpu_temp" -lt 50 ]; then
    echo 3 > /sys/class/thermal/cooling_device0/cur_state
fi

# HDD溫度偵測
if [ "$hdd_temp" -gt 45 ]; then
    echo 0 > /sys/class/thermal/cooling_device0/cur_state
elif [ "$hdd_temp" -gt 40 ]; then
    echo 1 > /sys/class/thermal/cooling_device0/cur_state
elif [ "$hdd_temp" -gt 35 ]; then
    echo 2 > /sys/class/thermal/cooling_device0/cur_state
elif [ "$hdd_temp" -lt 35 ]; then
    echo 3 > /sys/class/thermal/cooling_device0/cur_state
fi
# 風扇狀態偵測
fan_state=$(< /sys/class/thermal/cooling_device0/cur_state)
echo "[$timestamp] FAN_State : ${fan_state}"
```

```
root@LS-WVL885:~# bash temp.sh 
[2025-08-23 11:47:00] CPU Temperature: 55C
[2025-08-23 11:47:00] HDD Temperature: 37C
[2025-08-23 11:47:00] FAN_State : 2

#狀態

3 停止
```

**使用CRONTAB每分鐘執行腳本並寫入LOG**

```
* * * * * /bin/bash /root/temp.sh >> /root/temp.log 2>&1
```

##### **LED控制**

**關閉LED藍燈`echo 0 > /sys/class/leds/linkstation\:blue\:power/brightness`**

**開啟LED藍燈`echo 1 > /sys/class/leds/linkstation\:blue\:power/brightness`**
