The line it's talking about is: echo "$NEW_PWM" > "$FILE_PWM" So it looks like the "$FILE_PWM" variable is not valid. Remember, you have to change the variables under the comment "hwmon paths, hardcoded for one amdgpu card, adjust as needed" to whatever your system requires. To debug the variables I would execute the 4 lines that set HWMON, FILE_PWM, FILE_FANMODE, and FILE_TEMP from terminal and see where things are going wrong. I have to go now but I'll try to help you more tomorrow if you're still having problems. But once you have those variables set correctly the script should work. Here's what the service status output looks like on my system: Loaded: loaded (/etc/systemd/system/amdgpu-fancontrol.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2019-12-05 18:16:27 PST; 2h 28min ago Main PID: 836 (amdgpu-fancontr) Tasks: 2 (limit: 4915) Memory: 7.7M CGroup: /system.slice/amdgpu-fancontrol.service ├─ 836 /bin/bash /usr/local/bin/amdgpu-fancontrol └─14235 sleep 1 Dec 05 20:44:46 Entropod amdgpu-fancontrol[836]: changing pwm to 80 Dec 05 20:44:47 Entropod amdgpu-fancontrol[836]: current temp: 49000 Dec 05 20:44:47 Entropod amdgpu-fancontrol[836]: interpolated pwm value for temperature 49000 is: 90 Dec 05 20:44:47 Entropod amdgpu-fancontrol[836]: current pwm: 76, requested to set pwm to 90 Dec 05 20:44:47 Entropod amdgpu-fancontrol[836]: temp at last change was 48000 Dec 05 20:44:47 Entropod amdgpu-fancontrol[836]: changing pwm to 90 Dec 05 20:44:48 Entropod amdgpu-fancontrol[836]: current temp: 48000 Dec 05 20:44:48 Entropod amdgpu-fancontrol[836]: interpolated pwm value for temperature 48000 is: 80 Dec 05 20:44:48 Entropod amdgpu-fancontrol[836]: current pwm: 86, requested to set pwm to 80 Dec 05 20:44:48 Entropod amdgpu-fancontrol[836]: not changing pwm, we just did at 49000, next change when below 43000 -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
