Graphical X / Wayland renderer tests on the CI?

[Ambrevar]

In 232eddc I had to disable the renderer tests on the CI because they fail with:

<INFO> [14:02:56] Listening to socket #P"/tmp/nyxt-test.socket".
Unable to init server: Could not connect: Connection refused
error: XDG_RUNTIME_DIR not set in the environment.
error: XDG_RUNTIME_DIR not set in the environment
Nested Wayland compositor could not create display socket

Even though we are running in headless mode. I thought #2054 had figured it out, but apparently not.

Any idea?

well, first off: XDG_RUNTIME_DIR not set in the environment
you need to set it to i.e. export XDG_RUNTIME_DIR="/tmp/$(id -u)" and then make sure it exists via mkdir $XDG_RUNTIME_DIR

The connection refused part seems like a permission issue. Is there any code anywhere starting a window manager? How does it start? https://github.com/atlas-engineer/nyxt/blob/master/.github/workflows/tests.yml looked promising but couldn't find it.

You are correct, there is no code starting a window manager. What I do wonder is if the ubuntu-latest image includes a display server. It is possible/probable that is why it is failing.

I should have read more carefully, it includes Wayland! However, maybe something strange happens when there is no GPU/hardware for a display?

This is certainly possible, but CI doesn't provide much value at the moment.
