Got the same issue on Fedcora 30. It seems fixed after update to Ulauncher 5.4

[voneAbides]

Hello. I tried to update. Then I uninstalled and installed again. Still same Issue. Then Fedora 31 came out so I upgraded hoping that it could resolve the issue. Nothing worked.

[gornostal]

hi @voneAbides
I've tried on Fedora 31 and preferences work fine for me.
Did you install ulauncher by downloading an RPM file from the website?

BTW, I've just updated RPM links on ulauncher.io. Now we have only one RPM build for Fedora 29, 30, and 31.

[voneAbides]

Hello @gornostal . I reinstalled with new package from Ulauncher page, but still only blank (white) screen. Maybe definitive solution will be add Ulauncher to Flathub.

[gornostal]

What command did you run to install the app?

Could you describe what directories and files you see in /usr/share/ulauncher/preferences?

[voneAbides]

@gornostal In /usr/share/ulauncher/preferences I see only dist folder.
I used dnf install ulauncher.rpm. Maybe long term solution will be add Ulauncher to Flathub.

[gornostal]

I see only dist folder.

And I assume you don't have index.html in dist, right?
Are there any files in that directory?

[gornostal]

I just replied about Flathub in another issue.
It's a great thing, but I'd prefer keeping RPM and DEB up-to-date. At least for now.

[voneAbides]

Ok, sorry I forget that I uninstalled Ulauncher because it does not work. So I installed again. Same issue. I see these files and folders:

[voneAbides]

And preferences in gnome:

[gornostal]

Can you try running ulauncher from command line like this?

GDK_BACKEND=x11 ulauncher --no-extensions

Do you see any errors in the output?

[gornostal]

Error opening file /usr/share/ulauncher/preferences/dist/index.html: No such file or directory
I suppose this error is gone now since you have that index.html file, right?

[voneAbides]

Yes, error is gone. This is output of GDK_BACKEND=x11 ulauncher --no-extensions

[gornostal]

I see that ulauncher was running when you ran GDK_BACKEND=x11 ulauncher --no-extensions. Try to shut down the app first

[voneAbides]

Oh, sorry for that. This is the output:

[gornostal]

OK. that's better. And now could you open preferences while monitoring the output?

[voneAbides]

[gornostal]

anything unusual in the logs?

You can try one more thing:
If you run ulauncher with these arguments GDK_BACKEND=x11 ulauncher --no-extensions --dev you'll be able to right click on that white window and open Webkit inspector.
Then if you refresh the preferences by hitting Ctrl+R that could show an error in the Webkit inspector console.

Basically, it looks like preferences are not working due to some issue with webkit.

[gornostal]

Thanks for debugging. I need to think how that could happen...

[voneAbides]

Ok, by the way. Ulauncher is great! :D

[gornostal]

@voneAbides the problem is not clear. I'm pretty sure it's caused by some customization of your system. Maybe you've installed some package that affects Ulauncher or changed settings in some way.

We can check one more thing in that debug console, but this time could you run select "Network" tab, hit Ctrl+R, and and take a screenshot?

For me it looks like this:

[voneAbides]

@gornostal Sorry, I was busy last days.
Network looks like this:

[Raqbit]

Hi there! I'm having the exact same issue.

For me, index.html is loaded from file:///usr/share/ulauncher/preferences/dist/index.html#/preferences, with 3 /'s.

Could it be that when webkit loads the ./static/.. content, something goes wrong and it tries to load from file://null/ instead?

[gornostal]

@Raqbit you too use Fedora 31, right?
And by "having the same issue" you mean you see "Error opening file /usr/share/ulauncher/preferences/dist/index.html: No such file or directory" on a blank page?

file:///usr/share/ulauncher/preferences/dist/index.html#/preferences is the correct URL, btw.

Looking at @voneAbides's last screenshot I see that files are loaded correctly as there are no errors in the Network tab.

I need to reproduce it locally or in VBox somehow in order to fix the issue. So if you or @voneAbides can give me more details on how you configured your system that'd be great (What OS version, did you install any specific packages?, did you change any system settings that may affect this, etc)

[Raqbit]

@gornostal No, I'm using Ubuntu 19.10 with default (Yaru) theme and a Wayland session, I should have specified.

When I open the preferences, I get this white window:

and then when I give any input it makes the window transparent:

I must also note that the window is sometimes transparent from the get-go.

In devmode I find the following errors in the console tab:

and this is my Network tab:

Sometimes the window will half-render, but it won't be interactive as the javascript failed.

[gornostal]

Thanks for the screenshots.
I don't know why that JS error occurs. I would need to reproduce it myself in order to figure out what's wrong.

The weird thing is I'm running PopOS based on Ubuntu 19.10. However I'm on Xorg.
I've tried Fedora 31 with Wayland in VBox, it works fine there.

I'll try Ubuntu 19.10 with Wayland in VBox and other distros too.

[voneAbides]

New errors:

[gornostal]

ah I see the actual error now

I'm going to check the code. Hopefully I'll find why it can fail on that line...

[gornostal]

@voneAbides I don't know how to fix that particular error. I think it occurs because you may be running an old webkitgtk version. Try updating webkit2gtk3 package.

Also, could you open this URL in a browser please?
file:///usr/share/ulauncher/preferences/dist/index.html?browser=1#/extensions
It should open Preferences view with dummy content.

[voneAbides]

Ok. webkit2gtk3 version is 2.26.2. It's up to date. URL looks like this:

Shortcuts content is weird.

[gornostal]

That's what is expected. It uses dummy content when there's word "browser"
in a URL.

So this means that in Chrome it works, but in webkitgkt it doesn't. And
it's only on your machine. I haven't been able to reproduce this issue
elsewhere.

Ok, thank you very much. I will try to fix it.

[Raqbit]

Fyi, I'm on webkit2gtk 2.26.3 (which is the latest version on ubuntu at the moment), issue still occurring.

Very weird issue, and because you are not able to reproduce it on your own system, maybe this is graphics driver related?

[gornostal]

@Raqbit I doubt it's graphics related, but if you can check whether it is, that would be great.
I have an integrated graphics card on all of my laptops.

[krmax44]

I have this problem as well. Is it because of Wayland?

[krmax44]

Okay, so by removing all source maps (all lines with //# sourceMappingURL=... from dist) the error messages go away. The window stays as is, though...
