This program is an Ubuntu indicator to control the fan of Clevo laptops, using reversed-engineering port information from ECView.

It shows the CPU temperature on the left and the GPU temperature on the right, and a menu for manual control.

支持蓝天clevo-x370，我的笔记本型号是七彩虹将星x17 pro max，目前支持cpu和gpu的自动风扇调速，并且可以通过配置文件自由组合

sudo chown root clevo-indicator  && sudo chgrp adm clevo-indicator && sudo chmod 4750 clevo-indicator

For command-line, use -h to display help, or a number representing percentage of fan duty to control the fan (from 40% to 100%).

For Ubuntu 22.04:

sudo apt install libayatana-appindicator3-dev libgtk-3-dev install nlohmann-json3-dev
git clone https://github.com/grizzlei/clevo-indicator.git
cd clevo-indicator
mkdir cmake-build-release
cd cmake-build-release
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build .
sudo chown root clevo-indicator  && sudo chgrp adm clevo-indicator && sudo chmod 4750 clevo-indicator
sudo rm -rf /usr/local/bin/clevo-indicator
sudo make install
sudo chown root /usr/local/bin/clevo-indicator && sudo chgrp adm /usr/local/bin/clevo-indicator && sudo chmod 4750 /usr/local/bin/clevo-indicator

For older Ubuntu versions:

sudo apt-get install libappindicator3-dev libgtk-3-dev install nlohmann-json3-dev
git clone https://github.com/SkyLandTW/clevo-indicator.git
cd clevo-indicator
mkdir cmake-build-release
cd cmake-build-release
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build .
sudo chown root clevo-indicator && sudo chgrp adm clevo-indicator && sudo chmod 4750 clevo-indicator
sudo rm -rf /usr/local/bin/clevo-indicator
sudo make install
sudo chown root /usr/local/bin/clevo-indicator && sudo chgrp adm /usr/local/bin/clevo-indicator && sudo chmod 4750 /usr/local/bin/clevo-indicator

If you want to manually set custom fan control rules, create a configuration file at /etc/fan_config.json with the following content:

{
    "cpu": [
        { "temp": 10, "duty": 0 },
        { "temp": 20, "duty": 20 },
        { "temp": 30, "duty": 25 },
        { "temp": 40, "duty": 35 },
        { "temp": 50, "duty": 45 },
        { "temp": 60, "duty": 60 },
        { "temp": 70, "duty": 75 },
        { "temp": 80, "duty": 85 },
        { "temp": 90, "duty": 100 }
    ],
    "gpu": [
        { "temp": 10, "duty": 0 },
        { "temp": 20, "duty": 20 },
        { "temp": 30, "duty": 25 },
        { "temp": 40, "duty": 30 },
        { "temp": 50, "duty": 35 },
        { "temp": 60, "duty": 45 },
        { "temp": 70, "duty": 60 },
        { "temp": 80, "duty": 75 },
        { "temp": 90, "duty": 90 },
        { "temp": 95, "duty": 100 }
    ]
}

Each entry defines a mapping between temperature (temp) and the corresponding fan duty cycle (duty, in percentage).
The system will adjust the CPU and GPU fan speeds based on the temperature according to these mappings.

The executable has setuid flag on, but must be run by the current desktop user, because only the desktop user is allowed to display a desktop indicator in Ubuntu, while a non-root user is not allowed to control Clevo EC by low-level IO ports. The setuid=root creates a special situation in which this program can fork itself and run under two users (one for desktop/indicator and the other for EC control), so you could see two processes in ps, and killing either one of them would immediately terminate the other.

Be careful not to use any other program accessing the EC by low-level IO syscalls (inb/outb) at the same time - I don't know what might happen, since every EC actions require multiple commands to be issued in correct sequence and there is no kernel-level protection to ensure each action must be completed before other actions can be performed... The program also attempts to prevent abortion while issuing commands by catching all termination signals except SIGKILL - don't kill the indicator by "kill -9" unless absolutely necessary.
