Bonjour,
I upgraded to f42 from f40 using the dnf system upgrade, everything seems to be alright, except the default background which is missing on the logging screen (black) and also when users are logged (white).
I use lightdm and all files in /etc/lightdm and /usr/share/background seem to be correct....
What can I do?
Thank you.
F.P.

Use `journalctl` to look for relevant errors. Maybe start by running `journalctl --no-hostaname -b` in a terminal and looking for relevant messages. `man journalctl` provides lots of options to select records by "priority", search strings, etc.
Sometimes files are correct but selinux contexts are not.

It's a typo.
man journalctl: ... --no-hostname Do not show the hostname field of log messages originating from the local host. This switch has an effect only on the short family of output modes (see above).

In f40 the greeter config was:
background=/usr/share/backgrounds/default.png
When upgrading to f42 the greeter config is:
background=/usr/share/backgrounds/default.jxl
and the new file /etc/lightdm/lightdm-gtk-greeter.conf is installed as lightdm-gtk-greeter.conf.rpmnew
The same problem occurs with the default background for users but I don't know where are the config files...
If someone knows it, tell me!
