Getting graphics under qemu? #21

Closed DylanBartlett closed 6 years ago

DylanBartlett commented 6 years ago

I've created a core-image-sato ARM build using the container. I'd now like to emulate it but I'm getting a "Could not initialize SDL(No available video device)" error. Running the nographic option lets me boot to a login prompt but ideally, I need to get graphics working. I tried using the publicvnc option but a server never starts and the system never boots.

Is this possible under the container?

@DylanBartlett,

Ignore my last comment which I deleted. I wasn't aware of the publicvnc option that had been added to runqemu. I tested it out and it does work.

The reason you don't see a vnc server is because it is built into qemu. When you run with the publicvnc option, you will only get a small amount of output on the terminal. All of the rest will go to the vnc server.

However, you will also need to redirect the ports from the container to the outside. For example here is how I started the container:

docker run -it --rm -p 127.0.0.1:20000:5900 crops/poky

After that you should see all the output when you connect your vnc client to port 20000, or whatever you decided to use.

Ah, thanks for pointing that out to me rewitt1. I wasn't aware I had to forward the port like that. I'll try this out when I try working on my own Yocto layers.
