The website has the instructions right on the page, close to the end of page:

Ubuntu

Add the Ernst ppa-mesarc PPA.

Then run:

sudo apt install corectrl

Focal is supported, so this is literally everything you need.

r/linux4noobs on Reddit: Too noob to install CoreCtrl
April 7, 2024 -

Hi!

I know almost nothing about linux, what I know is thanks to SteamOS.

I've been researching how to undervolt my GPU on bazzite. I "only" need to install CoreCtrl and give it full control of AMD gpu but man I'm so overwhelmed. There's a lot of commands and even though the Gitlab site has an installation guide well. it is just guidance and they assme I have knowledge that I don't and it is not noob friendly, I have to edit something called GRUB bootloader which I don't even know how to find and there's no video guides to follow.

Maybe linux isn't just for me, I have this sensation I need to know a lot of programming just to do basic things as install software, Should I go back to Windows?. I'm happy with my SteamOS machine but I just wanted to undervolt my GPU (I also don't know how to do that and I will need to follow a guide or instructions) to keep temps a little bit lower and make sure they're always safe.

Thank you for reading.
