From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Installed Mint in a MacBook pro 16,1 and need help with touchbar (u.fail)

TL;DR: I've got a 2019 Macbook Pro, installed Linux Mint and I can't use the touchbar.

$ cat /sys/devices/virtual/dmi/id/product_name
MacBookPro16,1

Decided to install Linux Mint, with the help of this awesome website: https://t2linux.org/

My problem is I nuked the whole disk and the osx installation, so every time the instructions require to login in osx, I simply can't.

I was able to download the wifi firmware from here: https://github.com/AdityaGarg8/Apple-Firmware So, wifi works fine.

But touchbar doesn't work:

$ journalctl -k --grep=touchbar

Jun 15 21:51:35 apollo kernel: apple-touchbar 0003:05AC:8302.0007: tb: Failed to set touch bar mode to 1

If I do these steps:

$ sudo modprobe -r apple-touchbar
$ sudo modprobe apple-touchbar

Then I got:

$ sudo journalctl -k --grep=touchbar

Any help is appreciated. Thanks.
