Cannot open web-greeter
Closed this issue · 20 comments
Environment
- OS: Fedora 35
- web-greeter version: 3.3.0
Bug description
I cannot launch web-greeter at all in Fedora 35 after building it from source, even if using debug parameter, I get following errors:
2022-02-03 08:28:03 [ ERROR ] acpi - acpi.py:20 : init | ACPI: acpi_listen does not exists
2022-02-03 08:28:03 [ ERROR ] Greeter - Greeter.py:97 : init | lightdm_greeter_error: Unable to determine socket to daemon (1)
QWidget: Must construct a QApplication before a QWidget
Aborted (core dumped)
Steps to reproduce
Type web-greeter or web-greeter --debug in Terminal
Expected behavior
Web greeter would launch and I would be able to use my Windows XP login theme
Screenshots
You could try to add X-LightDM-Allow-Greeter=true inside your xsession (in /usr/share/xsessions/). Then, log out and log back in (with another greeter or lightdm's infinite loop will start); this should solve the Unable to determine socket to daemon error.
However, I cannot promise that it will work as there's an ongoing unknown issue with Fedora and web-greeter (#19), maybe related to some broke packages in Fedora.
Also, could you provide your Python version?
I've tried adding that line already, it did not work, here's a picture:
and my Python version is 3.10.2.
Also, do I need to have LightDM as the active display manager or can I still use GDM as of the time span?
You don't need to have LightDM as the main display manager, buy you still need it to be installed if you're using lightdm greeters in a Desktop Environment or Window Manager.
I'll try to check about the Fedora issue, but as I said before, surely it won't work with no apparent reason.
It should be fixed now in the latest commit: a8d2bf3
You can check it out and test if it does work~
Ok, but now I have a new issue trying to compile the latest commit:
make: ./venv/bin/pyrcc5: No such file or directory
make: *** [Makefile:70: ~/Downloads/web-greeter/build/web-greeter/resources.py] Error 127
Could you provide the full log?

Hmm, do a sudo make clean and make build, and provide the log~

It was made with an Ubuntu dockerfile with the required dependencies. Even if pyinotify fails to build in the venv, it should work as long as you have it installed globally (with fedora packages) and pyrcc5 is available inside ./venv/bin/ (unless pyqt5 fails in venv).
Ok, build succeeded but now I got this:
web-greeter
/usr/bin/env: ‘bash\npython3 /usr/lib/web-greeter $@’: No such file or directory
/usr/bin/env: use -[v]S to pass options in shebang lines
Nice, now seems a Makefile error. Try to build with the latest commit eeebb6b: sudo make clean and make build.
The content of /usr/bin/web-greeter should be the following:
#!/usr/bin/env bash
python3 /usr/lib/web-greeter $@
Do I need to have LightDM enabled or am I missing something?

LighDM is not needed to be enabled. Why does this happen? I don't know. web-greeter just doesn't work in Fedora for some weird reason... This may be related to #19.
Sadly, there's nothing I can do about it, though I could try more testing in the next days.
Oof, guess I'll just wait.
I managed to get nody-greeter working, but it's saying it cannot connect to socket. Also, my LightDM has error start request too quickly. How do I fix this? I'm one step closer to fixing this issue...
Create an issue in nody-greeter to track this and provide more info :D
Guess I'll mark this as solved then! :D
I'd like to think that this issue is not solved but a duplicate of #19. Anyways, thanks for putting your effort intro trying to solve this issue~
It is look like in case of "Unable to determine socket to daemon" web-greeter tries to show dialog:
web-greeter/src/bridge/Greeter.py
Line 99 in 60f0d1f
which produces the issue with Qt. As I understand QApplication is not fully created at the moment that is why it produces the sigabort.
I've commented out the dialog (99-108 lines) and web-greeter starts normally for me
