首先启用i8k模块
DSOE1024@DSOE1024-pc:~$ sudo modprobe dell-smm-hwmon force=1
DSOE1024@DSOE1024-pc:~$ sudo modprobe i8k force=1
DSOE1024@DSOE1024-pc:~$ i8kctl
1.0 1.2 2VJBGD3 80 3 3 2800 3100 -1 -1
如果遇到
modprobe: ERROR: could not insert 'dell_smm_hwmon': Exec format error
需要加载dell_smm_hwmon 模块
接下来安装控制工具
sudo apt install i8kutils
在sudo vim /etc/default/i8kbuttons和 sudo vim /etc/default/i8kmon 都写入 ENABLED=1
使用以下命令启用服务
sudo systemctl start i8kmon.service
sudo systemctl enable i8kmon.service
DSOE1024@DSOE1024-pc:~$ i8kctl
1.0 1.2 2VJBGD3 80 3 3 2800 3100 -1 -1
设置风扇停转
i8kctl fan 0 0
设置风扇满转
i8kctl fan 2 2
正常
i8kctl fan 1 1
如果想让服务开机启动，可以创建模块配置文件
sudo tee /etc/modprobe.d/dell-smm-hwmon.conf <<EOF
options dell-smm-hwmon force=1
EOF
sudo tee /etc/modprobe.d/i8k.conf <<EOF
options i8k force=1
EOF
添加到开机启动
echo "dell-smm-hwmon" | sudo tee -a /etc/modules
echo "i8k" | sudo tee -a /etc/modules
更新 initramfs
sudo update-initramfs -u
检查启动日志，应有如下输出：
DSOE1024@DSOE1024-pc:~$ journalctl -b | grep -E "dell|i8k"
