MacBook Air T2 chip issues

Hardware Support
1

I'm a 1st time Zorin user and pretty new to Linux in general, so I may be missing something simple. After installing Zorin on a MacBook Air with a T2 chip, any time the computer goes into "Suspend," it stops recognizing the keyboard and mouse. To wake the computer I need to plug in a USB mouse or keyboard. The computer doesn't have this issue after it is turned off or restarted.

I installed the OS using Zorin's official process for Macs with a T2 chip, then completed the recommended T2 updates, including those that enable WiFi connectivity and allow the speakers to function properly.

My keyboard doesn't work in BIOS, but the doc and USB slot are recognized in the system.

Here are a few other things I've tried:

I've also run: lsb_release -a

And:
CODENAME=jammy
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

And:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash atkbd.reset=1 i8042.nomux=1 i8042.reset=1 i8042.nopnp=1 i8042.dumbkbd=1"

Thank you in advance for any help you can offer.

Here is a snapshot of the computer info:

Hi Jim, welcome to the forum!

I don't have a Mac, so I don't have any first-hand experience of using Zorin on one. However, I noticed this article on the official help pages which talks about setting Zorin up on T2 Macs, so it might be of help to fix these issues:

Thank you @poropa6576 . I've worked through the Zorin official setup info. I should have mentioned that in my original post - I'll update that now.

Hi and welcome.

As Zorin 17.x is based on Ubuntu 22.04 I used this as the criteria for a Brave A.I. search via Mojeek which brought back the following:

Keyboard Not Working Ubuntu 22.04 MacBook Air T2

Users encountering issues with their keyboard not working in BIOS or after suspending their system in Ubuntu 22.04 on a MacBook Air with a T2 chip can try several troubleshooting steps. One approach involves ensuring that the correct firmware is installed for Wi-Fi and Bluetooth by downloading and running the firmware.sh script from a specific GitHub repository before installing Ubuntu. This script helps pull necessary drivers for these components over to the Linux side.

Another potential solution is to modify the /etc/default/grub file by setting the GRUB_CMDLINE_LINUX_DEFAULT variable to "quiet splash atkbd.reset" and updating the grub configuration with sudo update-grub , as suggested in a Quora post.

This modification aims to reset the keyboard upon resume from suspend.

If these methods do not resolve the issue, users might consider checking if the problem is related to a specific kernel version. For instance, a user reported that reverting to an older kernel version solved their keyboard issues after a kernel upgrade.

To revert to an earlier kernel, users can follow the instructions provided in the context to adjust the grub configuration accordingly.

In summary, addressing keyboard issues in Ubuntu 22.04 on a MacBook Air with a T2 chip involves ensuring proper firmware installation, adjusting grub settings, and possibly reverting to an older kernel version.

AI-generated answer. Please verify critical facts.
