Problem with a Touch Bar on macbook pro 13,3

[1755]

Hi! I would like to use ubuntu 19.10 on my macbook pro 13,3.

At first, I have tried a Live CD and everything except a sound works good. Also I have successfuly installed and run modules for touchbar while running the Live CD. But when I tried to reproduce these steps with installed ubuntu, I have not success.

sergey@sergey-MacBookPro:~$ uname -a
Linux sergey-MacBookPro 5.3.0-26-generic #28-Ubuntu SMP Wed Dec 18 05:37:46 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I have done the following commands:

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
update-initramfs -u -k all
reboot

sergey@sergey-MacBookPro:~$ lsmod | grep apple
apple_ib_als           20480  0
industrialio_triggered_buffer    16384  1 apple_ib_als

input_polldev          20480  1 applesmc
apple_gmux             24576  0
apple_bl               20480  1 apple_gmux
applespi               40960  0
video                  49152  1 apple_gmux

It looks like the module is loaded successfuly but the touchbar does not work.

One more wired thing. When I changed parameters for the module in my initramfs-tools/modules:

apple_ib_tb idle_timeout=-1 dim_timeout=-1 fnmode=1
applespi
spi_pxa2xx_platform
intel_lpss_pci

And then updated it and rebooted I have parameters unchanged:

Module: apple_ib_tb
Parameter: dim_timeout --> -2
Parameter: fnmode --> 1
Parameter: idle_timeout --> 300

@roadrunner2 Can you help me please?

Can you look in your dmesg to see if there are any errors reported there?

dmesg | grep applespi

Also, you didn't by any chance blow away the original EFI partition on the disk did you? It's important that that partition be preserved (with its original contents) or the touchbar won't work - see also Dunedan/mbp-2016-linux#52. In general you probably want to also keep the MacOS installation in case there are firmware updates, but that's optional.

@1755: Any update on this?

I also encountered this problem (MacBook Pro 13,3).

Also same here. I did have it working when I was dual-booting MacOS + Ubuntu, but now that i'm trying to wipe everything to install only Ubuntu, i can't seem to get this to work.
