displaylink-debian VS mbp-ubuntu-kernel

That is exactly it, proprietary driver. I use https://github.com/AdnanHodzic/displaylink-debian with excellent results with my Pluggable brand USB dock.

The monitor works fine with Windows 10 after I install the drivers. With the Ubuntu, however, things do not work. I tried installing the driver suggested by ASUS specific for this model, the most recent official Display Link driver, and the community script. All have give the same result: installation is said to be successful and asks me to reboot. I reboot and connect the screen. Screen turns on and keeps black. No display is detected. In Additional Drivers there is no drivers listed.

u/marvelggg was correct the issue was DisplayLink. Unfortnuately it wasn't possible to just reinstall their driver because they are not up to date with the current Linux kernel. I used calebanthony's advice from this page to get me back on track;https://github.com/AdnanHodzic/displaylink-debian/issues/745

If you use an Ubuntu or Debian based distro here is a DisplayLink driver: https://github.com/AdnanHodzic/displaylink-debian

(The lenovo branded dock is most horrible especially when used with Linux - needs drivers to be install. https://github.com/AdnanHodzic/displaylink-debian All others just work).

I bought a DisplayLink dock for my ubuntu laptops (2015 XPS and 2021 XPS) and it doesn't really work with either. It's quite maddening.

It requires a strange driver I would've preferred to avoid. I tried a strange workaround on both and neither really works; one still doesn't display through the DisplayPort or HDMI, the other doesn't work with the M.2 2280 built into the dock.

Download the .deb files from here (try the “alt” ones first) https://github.com/marcosfad/mbp-ubuntu-kernel/releases/tag/v5.7.19 and use sudo apt install FILENAMEHERE.deb.

You can use the mbp-ubuntu kernel, although it has not yet been updated with newer patches that are in mbp-arch, but you can build a kernel with those parches as described here. That keyboard/trackpad driver, apple-bce, is not in the main kernel yet. There are instructions for installing it as a dkms module here. In general, the t2linux wiki and the t2 linux discord server (linked to in the wiki a lot) are where the most up to date info on running linux on t2 macs is.

You’ll need to install an efi bootloader, i.e. grub, on a fat32 partition. If there’s an efi system partition on your external drive, then use that You probably will also want this patched kernel and keyboard trackpad audio and touchbar drivers, as described here.

If I remember correctly on my 2019 13” everything was working quite well except for the audio which would only output to the speakers and the wifi/Bluetooth not working. Battery was fine for me I can’t remember having to charge it more often than usual. Ubuntu on Touchbar Mac
