Making scaling governor changes permanent

[Member BottledSound]

Hello!

I’ve been having to keep changing my CPU governor in /sys/devices/system/cpu/cpuX directories individually back to ondemand after every restart, as it keeps reverting to performance. How do I make this change permanent? It’s still a fuss on my 2 core laptop, but I also use an 8 core desktop occasionally too, and it gets quite tedious to keep doing it all over again.

In general, though, I like this distro very much and I’m glad that with it my PCs will never become obsolete for the rest of my life 🙂

Cheers

Hi, please provide more information about your system (‘inxi -Fxz’ is a good start).

My tips:
1) Check what processes do change these files and explore why it occurs and options how to disable/prevent it from happening.
2) Write a script that automates the changes you make (simple copy or sequence of sed substitutions) and call it at an appropriate time automatically (e.g. via ‘cron’ at reboot)
3) Make these files read-only even for root. [This is potentially dangerous and it might break your system!]
