Good Evening,

I have installed Fedora 22 on a laptop with the following specs (as registered by the Details section of Settings:

Memory: 3.7 GiB Processor: Intel® Pentium(R) CPU P6100 @ 2.00GHz × 2 OS Type: 64-bit Graphics: Intel® Ironlake Mobile GNOME: Version 3.16.2 Disk: 54.8 GB

I want to increase the battery-life of my laptop. So I searched and found the following document:

This was the most recent one I could easily find, and it was for Fedora 19. Because I could not find a more recent version to try, I attempted to set up tuned.

So I:

[wbest@new-host-3 ~]$ su -
[root@new-host-3 ~]# yum install tuned
Yum command has been deprecated, redirecting to '/usr/bin/dnf install tuned'.
See 'man dnf' and 'man yum2dnf' for more information.
To transfer transaction metadata from yum to DNF, run:
'dnf install python-dnf-plugins-extras-migrate && dnf-2 migrate'

Last metadata expiration check performed 1:40:29 ago on Thu May 28 19:15:43 2015.
Package tuned-2.4.1-5.fc22.noarch is already installed, skipping.
Dependencies resolved.
Nothing to do.
[root@new-host-3 ~]# ^C
[root@new-host-3 ~]#

So then, I tried the steps to start and enable tuned located in the document cited above. Here is the output:

[root@new-host-3 ~]# systemctl start tuned
[root@new-host-3 ~]# systemctl enable
Too few arguments.
[root@new-host-3 ~]#

I get too few arguments. What am I doing wrong.

Thanks! Will

You didn't put what you wanted to enable in the command:

systemctl enable tuned

Thank you for answering so quickly! The directions in the PDF I linked just reads:

"To enable tuned to start every time the machine boots, type the following command: systemctl tuned enable"

Is there something else that has to come after that?

Thanks in advance,

Hrm... that's the wrong syntax. The guide should be fixed. The rest of the guide talks about tuned profiles and such, they should still apply.

So is there another way to have tuned auto-start when the computer turns on?

No, the command in my answer is the way to enable it to start on boot.

Oh boy am I stupid! I see, the answer now! Thanks for helping this dummy!
