You can install tuned : sudo dnf install tuned then sudo systemctl start tuned and sudo systemctl enable tuned

Then choose your profile :

  • tuned-adm active => active profile
  • tuned-adm list => list of available profiles
  • tuned-adm profile powersave => to active one.

To check the temperature : use sensors (sudo dnf install lm_sensors)

Thats the temps I get from sensors .

Any idea about the hibernate option ?

Basically I want to be able to watch a movie without the screen going black , and if i fall asleep i want the computer to go into hybernation if there is no activity

For hibernation after an idle time, you can try :

sudo vi /etc/systemd/logind.conf

Then uncomment and modify these 2 lines :


More info man 5 logind.conf

how do i uncomment ?

fvtssnow ( 2015-07-15 19:57:53 +0000 )edit

In the Terminal, run the command sudo vi /etc/systemd/logind.conf In the editor, move till the line #IdleAction=ignore with the arrows, press i (insert mode) and remove the character # (the line will be uncommented) and replace ignore by hibernate. Do the same with second line. Once done, press Escap (to quite the insert mode) and press ZZ (Z caps 2 times to save and quite).
