Hi, I'm using Debian 12 with xfce and I installed nody-greeter, it worked the first time I installed it with its default theme, but once I installed the WelcomeXP theme I can't login anymore, the greeter shows and the theme is perfect, but when I enter the password nothing happens. when I run

nody-greeter --debug

I get this message:

and

Hello! I just installed Debian 12 /w XFCE in a VM to try things out and was able to get things working fine following the README steps with minor changes (now using nody-greeter 1.5.2, NodeJS v18.x, and liblightdm-gobject-1-dev -> liblightdm-gobject-dev for Debian)

2024-02-20 19:48:02 [ WARN ] config.js 224: Theme config was not loaded:
    Error: ENOENT: no such file or directory, open '/usr/share/web-greeter/themes/WelcomeXP/index.yml'

This is unusual and I am curious to see what ls -l /usr/share/web-greeter/themes/WelcomeXP and ls -l /usr/share/web-greeter/themes look like. Files might be missing from that directory or the permissions may be off.

Also, I do not believe this is related to your issue but do make sure to specify user-session=xfce in /etc/lightdm/lightdm.conf since this theme relies on a configured default rather than checking which ones are available.

I checked for the user-session=xfce and it's there.

also nody-greeter works just fine, it just doesn't login while using this theme, other themes work fine.

What version of WelcomeXP are you using? Based on the file sizes and missing index.yml it looks like this is a very old version.

Try removing this installation by doing sudo rm -rf /usr/share/web-greeter/themes/WelcomeXP then reinstall /w steps 4-7 in the "WelcomeXP Installation" section of the README. Note that the README says git checkout v0.4.1 which is fine but you can skip this step since master branch is good right now I just haven't made a new release tag yet. Then again check with nody-greeter --debug to make sure the greeter starts up before logging out.

Hopefully this works.

I was using the latest version, I removed the installation and did it again according to the README but still the same issue appeared.

[mshernandez5]

1. Just to check what do ls -l /usr/share/web-greeter/themes/WelcomeXP and ls -l /usr/share/web-greeter/themes look like now?
2. Do you have the same issue with the simple theme? (in /etc/lightdm/web-greeter.yml set theme: simple) I ask because it is the only other default theme which relies on the default session being set correctly.

And yes, the same issue happens with simple theme, I think the problem is with nody-greeter?

Edit: it was the fault of nody-greeter, I reinstalled it and everything works perfectly now.
