evdi VS prost

git clone https://github.com/DisplayLink/evdi.git

So I'm currently on Ubuntu 22.10 with Mesa and asahi-edge kernel. You need both to allow using primary GPU as source output. I'm using evdi 1.13.1 with the correction to set the module to the 1.12.0 to run the script displaylink from Synaptics for Ubuntu.

The RPM version never worked for me. It's only useful for getting the services installed. After that clone the repo from https://github.com/DisplayLink/evdi and change to the devel branch. Run make and sudo make install. If you use SecureBoot you also need to sign the resulting evdi.ko with your key. After that restart displaylink.service or reboot and it should work. At least it did for me. I's been a while since I had to use it.

I'm afraid this might be a hardware issue, maybe with the cable. I don't have a second cable to swap out unfortunately. A new one won't be here until Saturday. And it seems like a hell of a coincidence for the cable to fail when there's other issues reported within the last few days that seem very similar.

Theres a bug in the 6.2 kernel right now with at least the evdi package (dont know about evdi-git) but can be fixed with a patch. Pr for it is already open but yet to be merged https://github.com/DisplayLink/evdi/pull/401

We've been using Rust with protobuf, but had to write lots of conversions from protobuf struct to actual DTO, since prost generates Options for nested types, and does not really support custom types. So I extended prost with the options that we needed. I might aim to also support protoc-gen-validate.

I'm prototyping an alternative protobuf code generator, with the aim to support more configuration and options. Prost does not have any facilities for implementing extensions, so it's a fork with edits in every single component.
