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.

And now it works for debian 10 and 11 too!

You need to have non-free repo enabled. Otherwise no way. Because it needs amd-firmware and its not on free repo. Follow this wiki first: https://wiki.debian.org/AtiHowTo

This first, according to dependencies declared in corectrl github:

sudo apt install libdrm-dev gcc cmake libqt4-svg libqt5svg5 qml-module-qtquick-controls qml-module-qtquick-controls2 qml-module-qtquick-controls qml-module-qtquick-layouts qml-module-qtcharts qml-module-qt-labs-platform libkf5archive5 extra-cmake-modules libqt5quickcontrols2-5 qtdeclarative5-dev libqt5charts5-dev libqt5svg5-dev qt4-linguist-tools qttools5-dev qttools5-dev-tools libkf5auth-dev libkf5archive-dev libbotan-2-dev libbotan-2-doc python3-botan qtdeclarative5-dev libqt5charts5-dev libqt5svg5-dev sysvinit-utils hwdata mesa-utils util-linux

DEBIAN 11: To install in debian 11, you need to remove the following packages from this list, because those packages DON'T EXIST ANYMORE in debian 11:

libqt4-svg qt4-linguist-tools

Then, continue the steps after "build" here: https://gitlab.com/corectrl/corectrl/-/wikis/Installation

It works. I tried. I might have missed some dependencies, but tell me if anything goes wrong post it here so I'll incorrect them.

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.
