evdi VS miraclecast

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

Edit: maybe micraclecast might help but it seems a bit complex to set up. Seems it doesn't support connecting to external displays yet. So not very useful for this use case.

I tried running Miraclecast on the Linux device, but it requires me to stop the network manager, which isn't acceptable as I need an internet connection to the device.

With that said, there are ways to do it. Miraclecast (see https://github.com/albfan/miraclecast ) is the most well-known Miracast implementation, but I've never been able to get it working - I got it to work as a sink, i.e. I was able to cast to it, but only at about 0.5 fps, and as I said, I was never able to get it to work to cast to another device. It looks like you might need to use a special branch of Miraclecast to do it, and it's a work-in-progress - I'm not sure if it's possible to do at this stage.
