Errors when running scripts/xephyr

[pawamoy]

Just pasting the log if it talks to anybody.

% ./scripts/xephyr                                                                                           (master|+1…) 20:23:14

I see missing fonts, unsupported keycode, error in cairo, and fatal error with xterm/x. Any idea how to fix that on my end? Did anyone encounter these kind of errors before?

[whatacold]

Hmm, it seems the AttributeError exception is caused by the wrong order of installing dependencies, check out issue #994

[pawamoy]

Thank you, it is better now.

I fixed the dbus/gobject error message by following the PyGObject installation instructions for ArchLinux at https://pygobject.readthedocs.io/en/latest/getting_started.html#arch-getting-started:

1. Open a terminal and enter your virtual environment
2. Execute sudo pacman -S python cairo pkgconf gobject-introspection gtk3 to install the build dependencies and GTK
3. Execute pip3 install pycairo to build and install Pycairo
4. Execute pip3 install PyGObject to build and install PyGObject

I still get this traceback though:

Traceback (most recent call last):

    return self.fmt.format(self._text)

And the xephyr window looks like this:

The terminal within the window is working, but then the test suite gets a lot of ERROR and FAILED (and it's kinda slow, don't know if it's normal):

It seems the errors are all caused by the same thing: AttributeError: module 'pytest' has no attribute 'config':

it's kinda slow, don't know if it's normal

It took me about 50 minutes last time I ran the test suites with a docker container (Here is the Dockerfile in case you're interested ), and I tried to speed it up with pytest-xdist, but resulted in too many errors, don't know why yet.

It seems the errors are all caused by the same thing: AttributeError: module 'pytest' has no attribute 'config':

I encountered this before, you can patch it with #1404 .

[pawamoy]

Alright, thank you very much @whatacold, I think I'm setup now 🙂 Your patch made the test suite work again. I'll close this issue and split it into new relevant ones.

[pawamoy]

Closing in favor of more focused issue #1436 and #1435. Will also open a PR to add a troubleshoot section in the docs!
