Comment 2 for bug 485899

Ugh, the bug here is that this program is amazingly misleading, even with step by step instructions. I went through the pwmconfig script probably for hours trying to figure out how these values are supposed to be set before I figured this out.

At the end, it says:

Do you want to set up its configuration file now (y)?
What should be the path to your fancontrol config file (/etc/fancontrol)?

Select fan output to configure, or other action:
1) hwmon0/device/pwm2 3) Change INTERVAL 5) Save and quit
2) hwmon0/device/pwm1 4) Just quit 6) Show configuration
select (1-n): 2

What we've been doing wrong is failing to select a fan output to configure. In my case, I needed to type "2" and hit enter, and then accept all the defaults. Before doing this, "show configuration" is blank. After doing this, "show configuration" contains stuff as you might expect.

The directions I was trying to follow the whole time are here: http://ubuntuforums.org/showthread.php?t=42737

My mistake was thinking all the automatically determined fan speed relationships were a new feature, the script was more automated, and I didn't need to follow all of the instructions on that page.

I'd say there's absolutely a bug here, but it's not that the script doesn't work. It's that it's far from obvious how to use it, and it doesn't give you any hint when you skip the necessary last step.
