xdg-settings: default-url-scheme-handler not implemented for xfce

[Caliandroid]

• Operating System (Linux/Mac/Windows/iOS/Android): Ubuntu 22.04.2 LTS

• Delta Chat Version: 1.38.1 v1.33.0-253-g5ff6e1e3 1687778551867

• Expected behavior: normal start-up

• Actual behavior: does not start or start with black window

• Steps to reproduce the problem: just start frehs installed app, same behavior with 1.38.1 appImage and installed *.deb

• Description: I've used deltaChat desktop since the early releases. Problems started with update in ~ June. I've tried to clean and purge all existing traces (.config/DeltaChat..) to start with a fresh session but it did not help either.

• Logs:

what was the last version of DC that worked for you?

"xdg-settings: default-url-scheme-handler not implemented for xfce" seems to be a common Electron problem, e.g. here are some similar reports:

• https://github.com/RocketChat/Rocket.Chat.Electron/issues/1513
• https://forum.obsidian.md/t/does-not-react-on-linux/13294
• https://github.com/vector-im/element-web/issues/14720

I did a quick grep inside the node-modules, it seems xdg-settings is executed by electron itself:

[node_modules]$ grep -r default-url .
grep: ./electron/dist/electron: binary file matches

But I am not sure it is the reason for the app not starting, this seems to be just a warning.

Sorry, but already deleted the last working version. I've used the AppImages, so no auto-update. I guess the last version was from Jan-Feb23... I need to try some old versions to be able to answer precisely

I am also using XFCE. I am using the latest build from master and it's fine. I will try deleting everything and trying again.

Edit: It's working fine for me with this setup:

DeltaChat v1.34.4 OR npm run start from the master xUbuntu 22.04 xfwm4 replaced with i3

logs:

16:58:00 ~/playground/DC/desktop (i3311*) $ npm run start

> deltachat-desktop@1.38.1 start
> electron . --devmode --disable-http-cache --translation-watch

So default-url-scheme-handler not implemented for xfce is just a warning.

The real problem is that Delta Chat "does not start or start with black window".

@Caliandroid Can you create a new account on the same computer and run DeltaChat and see if the issue still persists?

[Caliandroid]

Hello @farooqkz , yes it works now again. I've now restored the backup from my mobile app version and everything is up and running v.1.38.1, flatpack, still xubuntu 22.04.03.

Thank you
