Control device (ASUS fan) from Gnome shortcut

  • 772

After some search, the only reliable way I found to control the fan in my ASUS laptop was to issue this commands (as root):

turn on fans:

echo 0 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon7/pwm1_enable

turn off (automatic?) fans:

echo 2 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon7/pwm1_enable

How can I control these from a Gnome shortcut of another fast method? I tried making these path read-write from the user (although the privileges are reset on reboot) but then when I put this commands as commands for Gnome keyboard shortcuts they don't execute at all.

How can I make this run from a shortcut? and additionally (bonus), how can I make it run as root?

    Here is how to get the shortcut to work. We will go along with your original plan and not need root:

    1. Paste the following in /etc/tmpfiles.d/fans-askubuntu-1506330-1004020.conf . This will change the permissions at every boot to be writable.

      z /sys/devices/platform/asus-nb-wmi/hwmon/hwmon7/pwm1_enable 666

    2. Wrap your GNOME custom shortcuts in bash -c . The default way to launch commands does not support shell-specific syntax, just like how #! doesn't support it.

      bash -c "echo 0 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon7/pwm1_enable"
bash -c "echo 2 > /sys/devices/platform/asus-nb-wmi/hwmon/hwmon7/pwm1_enable"
