Inside the xorg.conf.d/ for example, we have three files:

00-keyboard.conf  10-monitor.conf  30-touchpad.conf

I know that the 2-digit number determine the precedence that each file is read so 00-keyboard.conf is read before 10-monitor.conf.

But I noticed that documentation on different sites all seems to use the same convention, e.g., using 10-monitor.conf for monitor configurations.

So, what I want to know is if there are numbers mapped to certain devices or if is just a convention that everyone stick with and I can use whatever 2-digit number that I want (according to precedences, of course). And if they are mapped, where can I find them?

I have searched about it but everything I found just mention what I have just said and doesn't mention if I can use other numbers or not. Even the xorg.conf[5] man page does not mention anything.

There is no mapping to devices or anything like that. The numbering is only used to enforce an order, and you don’t even have to name your configuration files with a number at the start — it’s just easier to reason about order with numbers.

So you can use any scheme you want.
