Fix Ubuntu 24.04 issues

Introduction

As the CPU (Intel® Core™ Ultra Processor [Series 2]) of Mind 2 AI Maker Kit is a quite new CPU, so current Ubuntu 24.04 LTS with Linux kernel 6.8 doesn't support well on it, current known issues list below:

AX211 Wi-Fi doesn't work
AX211 Bluetooth doesn't work
HDMI sound card doesn't work
GPU doesn't work

This documentation will guide you to fix these issues.

Preparation

As you need to download files from the internet, so you need a USB ethernet adaptor to access the network.

Disable the Secure Boot

You need to disable the Secure Boot to update the kernel, you can follow the steps below to disable the Secure Boot.

Reboot and press DELETE to enter BIOS setup menu, and then navigate to Security → Secure Boot, and setup to Disabled, press F4 to save and reboot.

Upgrade your system

$ sudo apt update
$ sudo apt full-upgrade -y
$ sync 
$ sudo reboot

After reboot, follow the steps below to upgrade the kernel to 6.11+ (kernel of Ubuntu 24.10):

$ wget https://security.ubuntu.com/ubuntu/pool/main//l/linux-signed/linux-image-6.11.0-13-generic_6.11.0-13.14_amd64.deb -P /tmp
$ wget https://security.ubuntu.com/ubuntu/pool/main//l/linux/linux-modules-6.11.0-13-generic_6.11.0-13.14_amd64.deb -P /tmp
$ wget https://security.ubuntu.com/ubuntu/pool/main//l/linux/linux-modules-extra-6.11.0-13-generic_6.11.0-13.14_amd64.deb -P /tmp
$ wget https://security.ubuntu.com/ubuntu/pool/main//l/linux/linux-headers-6.11.0-13-generic_6.11.0-13.14_amd64.deb -P /tmp
$ wget https://security.ubuntu.com/ubuntu/pool/main//l/linux/linux-headers-6.11.0-13_6.11.0-13.14_all.deb -P /tmp
$ sudo dpkg -i /tmp/linux-*.deb

Fix GPU issue

As Intel® Core™ Ultra Processor (Series 2) GPU is supported from NESA 24.2.2 so you need to upgrade the MESA packages:

$ sudo add-apt-repository ppa:kisak/kisak-mesa
$ sudo apt update
$ sudo apt full-upgrade -y

The Ubuntu 24.04 repositories contain compute packages for various Intel graphics products. To install those packages, use the following commands:

$ wget -qO - https://repositories.intel.com/gpu/intel-graphics.key | \
  sudo gpg --yes --dearmor --output /usr/share/keyrings/intel-graphics.gpg
$ echo "deb [arch=amd64,i386 signed-by=/usr/share/keyrings/intel-graphics.gpg] https://repositories.intel.com/gpu/ubuntu noble client" | \
  sudo tee /etc/apt/sources.list.d/intel-gpu-noble.list
$ sudo apt update
$ sudo apt install -y libze-intel-gpu1 libze1 intel-opencl-icd clinfo intel-gsc

The commands listed above install all the essential packages needed for most users, aiming to minimize the installation of unnecessary packages. However, if you plan to use PyTorch, install libze-dev and intel-ocloc additionally:

$ sudo apt install -y libze-dev intel-ocloc

Add user to render group and reboot the device:

$ sudo gpasswd -a ${USER} render
$ newgrp render
$ sync
$ sudo reboot

After reboot, to verify that the kernel and compute drivers are installed and functional, run clinfo:

$ clinfo | grep "Device Name"
  Device Name                                     Intel(R) Graphics [0x64a0]
    Device Name                                   Intel(R) Graphics [0x64a0]
    Device Name                                   Intel(R) Graphics [0x64a0]
    Device Name                                   Intel(R) Graphics [0x64a0]

Fix Wi-Fi issue

Download and install the Wi-Fi driver

Follow the steps below to download the Wi-Fi driver:

$ sudo apt update
$ sudo apt install -y git build-essential gcc-14 net-tools
$ cd ~/Downloads
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git -b release/core91 --depth=1

Build and install the Wi-Fi driver:

$ cd ~/Downloads/backport-iwlwifi
$ make defconfig-iwlwifi-public
$ make -j10
$ sudo make install
$ sync

Update the Wi-Fi firmware

You need to follow the steps below to update the Wi-Fi firmware:

$ wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-bz-b0-gf-a0-94.ucode -P /tmp
$ wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-bz-b0-gf-a0.pnvm -P /tmp/
$ sudo cp /tmp/iwlwifi-bz-b0-gf-a0* /lib/firmware/
$ sync

Then you need to reboot your device to take effect.

$ sudo reboot

Check Wi-Fi status

After reboot, you can check the kernel log about the Wi-Fi driver.

$ sudo dmesg | grep iw
