Greeter freezes after clicking on clock

[paescuj]

After clicking on the clock in the antergos greeter theme, the user and password fields appears but the greeter kind of freezes - the cursor can still be moved around but I'm unable to click on anything or fill in the password field. Similar behaviour also in simple theme. Maybe the greeter has some problem when getting information about the user?

Versions used:

• LightDM - 1.16.7
• lightdm-webkit2-greeter - master
• Webkit-GTK - 2.12.5

Couldn't find anything interesting in the logs:

Could you check the webkit dev console to see if any errors show up? (just right-click and select "Inspect Element")

[paescuj]

Thanks for your quick response!

Already did that, there was exactly the same output as in the x-0-greeter.log plus a few CSS errors from bootstrap and font awesome (I guess those are irrelevant)...

[lots0logs]

Which distro (including version) are you using?

[paescuj]

I'm using Gentoo with kernel version 4.4.26

[lots0logs]

Hmm..are you able to use any later versions of lightdm and webkit2gtk? Well lightdm isnt the problem for sure, really its most likely an issue with webkitgtk. There has been significant progress made in regards to its performance and stability since the 2.12 series...

[paescuj]

Just tested it with the latest versions available on Gentoo:

• WebkitGTK - 2.14.2
• LightDM - 1.21.3

Still the same issue. No interesting output in the logs or in the console. I've noticed that the profile picture doesn't get displayed, while in the gtk-greeter it does.

[lots0logs]

Which graphics stack does your system have? Which driver are you using?

[paescuj]

It is a integrated Intel HD Graphics 4000 and the kernel driver in use is i915.

[lots0logs]

@paescuj Could you let me know if you still see this issue with the latest release?

[paescuj]

Unfortunately still the same issue using the latest release. However the profile picture is displayed now.

There must be a problem during the pre-authentication process. Possibly due to some special configuration / software compilation on my system. I'll try to figuring out more about this.

[lots0logs]

Are you using systemd on your system? If so could you check the journal after the issue occurs and post anything you find that is related to the greeter?

[paescuj]

Just switched from OpenRC to systemd. Now, the greeter shows a black screen with the following text:

Error opening file: No such file or directory

This is the output of the journal:

Does the greeter relies on gnome? Because I don't have the gnome environment installed - I'm using awesome wm.

[lots0logs]

No it doesnt need the full gnome stack. You can see the dependencies on the README. Could you check to see if this directory exists and is not empty? /usr/share/backgrounds

[paescuj]

Yes, it does exist and there is a picture in it.

[lots0logs]

You followed the instructions on the README to build and install the greeter correct? Could you check the file permissions on /usr/share/lightdm-webkit/themes and make sure the mode is 755? Also check that the theme's index file exists: /usr/share/lightdm-webkit/themes/antergos/index.html

[paescuj]

Yes, I did. I can confirm that the mode of /usr/share/lightdm-webkit/themes is 755 and the file /usr/share/lightdm-webkit/themes/antergos/index.html exists.

[lots0logs]

Sorry this is difficult to debug remotely (obviously). Does pressing Tab allow you to focus the password entry field? When you checked the webkit dev console did you switch it to the "Console" tab and then ensure the filters were set to show all messages?

[paescuj]

Yes, it really is - thank you for your efforts!

No, the theme doesn't get loaded at all. Just the following:

There aren't any messages in the "Console" tab.

[lots0logs]

Could you post the contents of /etc/lightdm/lightdm-webkit2-greeter.conf here?

[paescuj]

[lots0logs]

Hmm..I am at a loss here. I don't see how it possible that you are seeing errors in the console that mention antergos-wallpapers :confused: It would be helpful to know exactly what the error said though.

[paescuj]

I never had errors mentioning antergos-wallpaper. Instead the greeter has freezed (https://github.com/Antergos/lightdm-webkit2-greeter/issues/95#issue-195595325) and I was unable to login.

Then I switched from OpenRC to systemd (https://github.com/Antergos/lightdm-webkit2-greeter/issues/95#issuecomment-270253109) and now I'm getting a black screen.

Probably my report in this ticket is a bit messy, so if you like to, you can close this issue and I will add a report about the black screen to issue #46.

[lots0logs]

I must have gotten your issue mixed up with some other issue. Sorry :grimacing:

[lots0logs]

@paescuj Could you open a new issue for the black screen problem? Be sure to include your logs. Thanks.
