Various errors with any theme

[p3lim]

Trying to get LightDM set up on my laptop, been running into various issues with every theme I've tried to use, including the two that it comes with.
When running with lightdm-webkit2-greeter and the theme "antergos" I get this:

** (WebKitWebProcess:1163): CRITICAL **: lightdm_greeter_ensure_shared_data_dir_sync: assertion 'priv->connected' failed
undefined:13824:37: CONSOLE ERROR: TypeError: null is not an object (evaluating 'user_data_dir.substr')

At which point it will ask to load default or fallback theme.
When using the "simple" theme I get this:

file:///usr/share/lightdm-webkit/themes/simple/index.html:194:10: CONSOLE ERROR ReferenceError: Can't find variable: lightdm

Configs for both lightdm and lightdm-webkit2-greeter are stock, except for setting the correct greeter in /etc/lightdm/lightdm.conf and the theme in /etc/lightdm/lightdm-webkit2-greeter.conf.
Running lightdm --test-mode --debug flashes an empty window on the screen then closes, lots of errors about permission denied. Elevating this results in a black screen w/ blinking cursor, have to force reset at this point.

Versions/OS:

• archlinux x86_64, everything up-to-date at time of posting
• lightdm: 1:1.20.0
• lightdm-webkit2-greeter: 2.2.2 (AUR)
• webkit2gtk: 2.14.3

I'll supply logs if needed, just tell me which one(s).

Hi, did you install it using the PKGBUILD in the AUR? It looks like there's an issue with the shared data directory (typically this is located at /var/lib/lightdm-data/$username. Does that directory exist on your system?

[p3lim]

Yes, used the PKGBUILD from AUR to install it, that directory exists.

[lots0logs]

Could you try installing using the commit I just made and let me know the result? You can do it using this updated PKGBUILD in the place of the one in the AUR: http://paste2.org/zL7U7taP

Still getting the same errors, build went fine tho'.

[lots0logs]

That shouldnt be possible. Did you bump the pkgrel when you built it?

[p3lim]

Yep

Just tested the second commit, still the same (Github decided not to refresh that part of the conversation for me, didn't notice it until I reloaded the page).

[lots0logs]

This error is no longer possible with the latest commit:

CONSOLE ERROR: TypeError: null is not an object (evaluating 'user_data_dir.substr')

There is a bug in glib-compile-resources where it doesnt notice changes to gresource files during subsequent builds. Are you reusing the same build directory? If so, try removing it completely and then rebuilding.

[lots0logs]

Could you post the full contents of lightdm.log and x-0-greeter.log if the issue still occurs? Thanks.

Did this.

I stopped getting this error:

CONSOLE ERROR: TypeError: null is not an object (evaluating 'user_data_dir.substr')

And instead it let me know that /usr/share/backgrounds didn't exist, which I've now made.
The "antergos" theme still gets javascript exceptions (no detail in the output from lightdm-webkit2-greeter), and the "simple" theme still gets the same errors as before.

Here is the entire contents of /var/log/lightdm/ when using the "antergos" theme: https://gist.github.com/p3lim/733e961e5e6c9742b9114c92a88e4062

Could you enable debug mode in the config file and then check the webkit dev console inside the greeter (Right-Click>>Inspect Element>>Console)

[p3lim]

With debug mode on I'm unable to right-click when using the antergos theme.
When I mouse over anything in the dev console it turns black, this was on the simple theme (only one I could seem to get a context menu on).

If I left-click anywhere in either theme the whole screen goes black (cursor still visible, right-clicking doesn't seem to work).

Same issue. Greeter locks up when attempting to open devtools.

I think the devtools issue is a bug in webkitgtk actually. I remember seeing an email from the mailing list not too long ago.
