'Overriding invalid values'

[LinuxOnTheDesktop]

I have the latest version of your program and it is reporting errors in my config file but I am afraid I cannot find them. So I am inclined to think that either the program is not parsing the config properly or else it could at least give more informative error messages :)

Here are the errors.

Your undervolt values should be negative. See if it still happens if you add a minus sign in front of all undervolt entries.

Making the values negative did indeed fix the problem. This will be something that trips many people up, I think. After all, the sections are entitled _under_volt. I suggest that you put something about this as a comment at the top of the default conf file. Thanks for the help.

[nariox]

The Readme states that the values must be negative (it also has an example). But I see how it could be confusing by only looking at the conf file. You can check the relevant section of the readme here: https://github.com/erpalma/throttled#configuration

[LinuxOnTheDesktop]

Ah. Thanks. Still, you might as well stick the point in the conf file as well, no?
