T2 Ubuntu Kernel

Ubuntu/Mint kernel with Apple T2 patches built-in. This repo will try to keep up with kernel new releases.

Note for Debian users :- Since Debian doesn't support the kernels released in this repo, Debian users are suggested to use this fork to get compatible kernels.

Build Kernel Package

This project is closely inspired by mikeeq/mbp-fedora-kernel and marcosfad/mbp-ubuntu-kernel. Thank you @mikeeq and @marcosfad for the scripts and setup.

Special thanks to @Redecorating for the CI.

If this repo helped you in any way, consider inviting a coffee to the people in the credits (links given here).

INSTALLATION

Using the apt repo

Firstly add the t2-ubuntu-repo apt repo. You need to follow these steps to add it:

  1. Identify your release codename. It is:

    a) jammy for Ubuntu 22.04

    b) mantic for Ubuntu 23.10

    c) noble for Ubuntu 24.04

    You can also run lsb_release -a to identify your codename.

  2. Run the following (taking noble as the example, just replace it with your release codename in the first line):

CODENAME=noble
curl -s --compressed "https://adityagarg8.github.io/t2-ubuntu-repo/KEY.gpg" | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/t2-ubuntu-repo.gpg >/dev/null
sudo curl -s --compressed -o /etc/apt/sources.list.d/t2.list "https://adityagarg8.github.io/t2-ubuntu-repo/t2.list"
echo "deb [signed-by=/etc/apt/trusted.gpg.d/t2-ubuntu-repo.gpg] https://github.com/AdityaGarg8/t2-ubuntu-repo/releases/download/${CODENAME} ./" | sudo tee -a /etc/apt/sources.list.d/t2.list
sudo apt update

Currently, 2 types of kernel variants are available. You can use anyone as per your choice:

  1. Mainline kernels:

    If you want to install Mainline kernels, install linux-t2 package:

    sudo apt install linux-t2

    Note: The Mainline kernels are shipped by default if you have used the iso from T2-Ubuntu, but you STILL HAVE TO INSTALL THIS to receive kernel updates after installing Ubuntu

  2. LTS kernels:

    If you want to install LTS kernels, install linux-t2-lts package:

    sudo apt install linux-t2-lts

  3. Mainline Xanmod kernels:

    If you want to install Mainline Xanmod kernels, install linux-t2-xanmod package:

    sudo apt install linux-t2-xanmod

  4. LTS Xanmod kernels:

    If you want to install LTS Xanmod kernels, install linux-t2-xanmod-lts package:

    sudo apt install linux-t2-xanmod-lts

Now, whenever a new kernel is released, you can use Software updater or run sudo apt upgrade to get it.

Changing kernel variant:

If you want to change the kernel variant, say from Mainline to LTS, first install the package of the kernel, and then remove the current kernel. Eg, if you wanna switch to LTS from Mainline, run:

sudo apt install linux-t2-lts
sudo apt remove linux-headers-$(uname -r) linux-image-$(uname -r)

Simply replace linux-t2-lts in the above command with the kernel variant you want to use.

Download package manually

Download the .deb packages of linux-headers and linux-image of the kernel you wish to install from the releases section.

Install linux-headers first and then linux-image using apt and restart your Mac. In case you do not know how to do so, follow the instructions given below. Else you are good to go.

On terminal, type sudo apt install and then drag and drop the linux-headers file to the terminal and press enter/return key.

Do the similar process for linux-images package.

Restart your Mac.

Building yourself

Clone the repo using

git clone https://github.com/t2linux/T2-Ubuntu-Kernel

Open a terminal window and run

cd T2-Ubuntu-Kernel
sudo ./build.sh

The kernel shall take around an hour to compile. After that you shall find three .deb packages in /root/work.

Install the linux-headers package first using apt. In case you do not know how to do so, follow the instructions described in the above The easy way section. Similarly install the linux-image package too.

Restart your Mac.

You may then delete the /root/work directory using sudo rm -r /root/work to free up space.
