Ubuntu – What does “ACPI PPC Probe failed Starting version 219 ” mean exactly

15.04acpidriversnvidia

I've recently installed Xubuntu 15.04 on my desktop

The video playback was kinda slow and buggy so I installed the nvidia drivers (the gpu is an onboard 7025)

As some people, I get the "ACPI PPC Probe …" message, but after 20 seconds or so, the system boots just fine, also the video playback is fine and there doesn't seem to be any graphic issues

My question is: Should I be worried about that message popping every time I boot? and what does it exactly means?

I didn't found any answers to that, just workarounds for people who can't pass the message

Best Answer

The message is harmless. In fact it is 2 messages

First:

ACPI PCC Probe failed

It is a new built-in feature of the 3.19 kernel. It just states that it did not found some PCC software or hardware. I don't know much about it.

Second:

Starting version 219

This is a message from systemd, stating it is starting. 219 is the systemd version.

You can safely ignore them.
