Argon Mini FAN PWM doesn't work on Ubuntu

Hi All,

I order 2 pcs of Argon Mini Fan for my rpi 4.
I used the user manual to create the necessary config.txt file in boot folder, however it did not work.
I tried to look up what could cause the problem and it seems to me that sincs I use Ubuntu 21.04 and not raspbian it is probably not supported.
I then tried to install the script, but it did not work either, probably because that script as I could tell is for the Argon One Fan.

Is there a script for the Argon mini or does anyone have some suggestion where did I go wrong?

Thanks in advance.

Might be late to the party, just for anyone find this post (I find this post before I get the solution, so :wink: ).

The spirit is to find the correct directory for “config.txt” in ubuntu. The directory structure of raspbian and ubuntu are a little bit off, so please follow this link:

So just follow the guide for raspbian but change /boot/firmware/config.txt instead and you are good to go.
