Can't get past SDDM after recent upgrade

D@rkmind · 2025-06-28 16:24:33

I updated all my machines to the latest version this morning. All went well except one laptop. Suddenly SDDM fails to loads the style and shows the error message:

The current theme cannot be loaded due to the errors below, please select another theme.

file:///usr/share/sddm/themes/breeze/Main.qml: module "1" is not installed

In case I type the password and proceed, KDE loads into a blank screen and the only thing that work is the right-click menu. Though opening any dialog windows from that menu result into the app crash.

I've checked the entire FS for *.pacnew files - there're none. I tried to compare the list of packages with the other machines (that work), I can't see any difference.

I've tried re-installing packages like breeze, sddm and any packages that have them in their name.

What else can I do to troubleshoot it?

Try running fc-cache -rs . If it gives you a core dump, run sudo fc-cache -rsv , and try to get an idea what font it's having trouble with, and uninstall it.

I recently had to uninstall ttf-google-fonts-git due to fontconfig having all sorts of problems with one of the fonts in it, and sddm not loading was one of the issues this caused.

(Bear in mind if this is the problem, you may have to go around changing fonts on things, or installing alternate packages to get the fonts you need. ttf-google-fonts-typewolf seemed like a decent alternative to ttf-google-fonts-git.)

D@rkmind · Yesterday 21:48:31

I've just tried running both commands - they didn't show any failure or errors.

I also checked what font-related packages are installed in the system. Both working and problematic machines have exactly the same list:

adobe-source-code-pro-fonts
adwaita-fonts
cantarell-fonts
fontconfig
gnu-free-fonts
gsfonts
lib32-fontconfig
libfontenc
libxfont2
noto-fonts
noto-fonts-emoji
python-fonttools
xorg-fonts-encodings

The original error looks quite strange. It's like there's a bug in the source code and it failed to substitute "%1", so instead of the actual module name that it can't load, it's printing just "1"...

What else can I do to troubleshoot it?

1. pacman log for what was actually updated
2. system journal

Possibly https://archlinux.org/news/plasma-640-w … re-on-x11/ ?

Also, these are the entries that I'm seeing in journalctl when SDDM fails to load the theme:

I'll compare pacman.log from different machines on that day.

Pacman shows that plasma-desktop doesn't have any alterations:

Ok,so what does the journal look like after the actual session started?
Also let's see whether other packages (kdeclarative? qt6-declarative?) are damaged:

sudo LC_ALL=C pacman -Qkk | grep -v ', 0 altered files' | grep -v backup

There're some errors in polkitd (not sure if related), but mainly there're lots of other errors with the same message (module \"1\" is not installed) coming from all sorts of components:

(I find it strange that in one of the messages it actually refers to "1" as a style name)

Package list looks harmless, module "1" is obviously not a thing,

Did you mess around w/ testing or 3rd party repos?

D@rkmind · Today 09:06:41

Previously I used to have "community" repo enabled, but never testing or any 3rd party

However, I don't see "DayNightComponent.qml" in the logs either. Why would it be related?
