I would like to execute a command which requires sudo privileges. Specifically, I want to set my CPU frequency to a performance governor using the following script.

sudo cpufreq-set -g performance

What I have done so far is I have added this custom command from System Settings -> Applications -> Startup. I also changed the permission of the newly created file from ~/.config/autostart. However, the sudo command is still not executing. Are there any other ways to do this?


If you have a laptop, you can use TLP to automatically set it.

If you prefer a more simple method, you can create a systemd service that will execute at startup.

sudo io.elementary.code /etc/systemd/system/cpuperformance.service

Description=Set CPU performance governor

ExecStart=/usr/bin/cpufreq-set -g performance


Close that file and then execute sudo systemctl daemon-reload && sudo systemctl enable cpuperformance.service.

If you want to disable this in the future you can use sudo systemctl disable cpuperformance.service and sudo rm /etc/systemd/system/cpuperformance.service to remove the file.

  • So laptop power management tools are not installed by default in elementary OS? Is TLP the only way to do this kind of high-performance configuration? I looked into Debian and it seems that TLP is also not included by default in their laptop-related packages installed via tasksel laptop command. – Orlando Lewis Sep 20 '20 at 15:24
  • No, TLP is not installed by default. And the method I described works on laptops as well however I prefer to use TLP since it allows for many more configurations that you'll probably want to change anyway if you're getting into this sort of thing. – Maccer Sep 20 '20 at 16:04
  • The thing is, I don't really like installing packages which could have the possibility of conflicting. I already have cpufrequtils installed and actually, it is Debian's recommended way of configuring the CPU governor to use. If I just want to maximize the CPU frequency regardless whether I am on battery or AC power, do I really need to have the tlp package included? – Orlando Lewis Sep 20 '20 at 22:24
  • As I said, you don't need to install tlp. Using a systemd service will work just fine. – Maccer Sep 21 '20 at 20:00
