Problem on 13,3 (15") with Ubuntu 18.04.4

nndei commented 4 years ago

Hello,

I am a very big noob who doesn't understand most of the guide. However, I did the following steps but can't make this touchbar work.

1) checked my kernel with command uname-a and got 5.3.0-42-generic 2) therefore jumped to load the two spi_pxa2xx_platform and spi_pxa2xx_pci with the command modprobe 3) sudo -i + password to become root 4) copied and pasted code:

echo -e "\n# applespi\napplespi\nspi_pxa2xx_platform\nintel_lpss_pci" >> /etc/initramfs-tools/modules

apt install dkms
git clone https://github.com/roadrunner2/macbook12-spi-driver.git /usr/src/applespi-0.1
dkms install -m applespi -v 0.1

5) sudo reboot

Nothing has changed, how do I complete the steps and have a touchbar working? I am sorry, but I have not found any help on checking the initramfs/initrd for modules, also what if they're not there?

Best regards, Neri

Apologies for the slow reply. First of all, that change to /etc/initramfs-tools/modules isn't necessary, as those modules are for the keyboard/trackpad driver which appears to be already working fine (and besides, you just added a comment to that file, i.e. it's a no-op anyway). And similarly, the modprobe isn't necessary either.

Now, let's see why the touchbar isn't being activated. Here are some commands to run to gather some more info:

lsusb -t
sudo dkms status applespi
lsmod | grep apple
dmesg | grep apple

The first command should give output similar to this:

/:  Bus 06.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 10000M
/:  Bus 05.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 480M
/:  Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 10000M
/:  Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 480M
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/8p, 5000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/16p, 480M
    |__ Port 3: Dev 2, If 0, Class=Video, Driver=uvcvideo, 480M
    |__ Port 3: Dev 2, If 1, Class=Video, Driver=uvcvideo, 480M
    |__ Port 3: Dev 2, If 2, Class=Human Interface Device, Driver=usbhid, 480M
    |__ Port 3: Dev 2, If 3, Class=Human Interface Device, Driver=usbhid, 480M

The last four lines are the iBridge interfaces.

Next, the dkms output should show the applespi module as being installed for your kernel. If it isn't, try installing it again.

Then, the lsmod output should contain at least apple_bridge and apple_ib_tb. If not, try loading them explicitly (sudo modprobe apple_ibridge).

And lastly, the kernel messages should show some activity relating to the ibridge and touchbar drivers being activated.

Hello, thank you for the reply.

Firstly, the lsusb -t command outputs your exact output, with an added line between the Bus 06 and Bus 05 lines: |__ Port 2: Dev 2, If 0, Class=Vendor Specific Class, Driver=r8152, 5000M

sudo dkms status applespi gives no output.

lsmod: applesmc 20480 0 input_polldev 20480 1 applesmc apple_gmux 20480 0 apple_bl 20480 1 apple_gmux applespi 40960 0 video 49152 1 apple_gmux

And lastly, dmesg outputs:

Firstly, the lsusb -t command outputs your exact output, with an added line between the Bus 06 and Bus 05 lines: |__ Port 2: Dev 2, If 0, Class=Vendor Specific Class, Driver=r8152, 5000M

That's fine - this is a USB ethernet adapter you've apparently plugged in.

sudo dkms status applespi gives no output.

Ah, this is our problem then - for some reason the dkms module did not get built and installed. Can you rerun sudo dkms install -m applespi -v 0.1 and show its output?

nndei commented 4 years ago

Man you're a wizard for that adapter thing!

Output: Error! Could not find module source directory. Directory: /usr/src/applespi-0.1 does not exist.

roadrunner2 commented 4 years ago

So it looks like you never ran the git clone command, or if you did that it failed. Please run that again (prefix it with sudo if you aren't already root), and then run the dkms install.

nndei commented 4 years ago

Hello, thank you for the reply. I tried again installing the git, but then I still get the same Error as before.

If I try to run the git again, I get fatal: destination path 'macbook12-spi-driver' already exists and is not an empty directory.

roadrunner2 commented 4 years ago

What is the exact command you're running? It looks like you're missing the last argument, causing it to clone into the macbook12-spi-driver directory instead of into /usr/src/applespi-0.1. To repeat, the full command should be:

sudo git clone https://github.com/roadrunner2/macbook12-spi-driver.git /usr/src/applespi-0.1

nndei commented 4 years ago

All runs smoothly! Sorry for my inexperience.

Thank you!
