Theme is not working anymore: Main.qml: Library import requires a version

[GaetanLepage]

Hi,

The theme has stopped working for me. Here is the log resulting from my trying the greeter in test-mode:

❮ sddm-greeter --test-mode --theme /run/current-system/sw/share/sddm/themes/where_is_my_sddm_theme/

As a comparison, here is the log for the maya built-in theme, which works fine:

So the issue seems t be this Library import requires a version message that directly precedes the Fallback to embedded theme and is not present in the maya logs.

Same with X11

Try qt5 theme

[ElrohirGT]

Can confirm this happens with NixOS too! I'll try to pack the qt5 theme maybe that'll work...

[ElrohirGT]

The qt5 theme works! At least when I try to run it with:

sddm-greeter --test-mode --theme {path to my config dir}

The image appears blurred... This was not the case with the previous theme, do the configs change between the two?

[stepanzubkov]

Oh, I accidentally left blurRadius=32 in the theme.conf. Setting blutRadius=0 will solve your problem

[stepanzubkov]

Fixed in main branch

[GaetanLepage]

Thank you very much !

[GaetanLepage]

Actually, I still encounter the error using 1.9.2...

[stepanzubkov]

Which error: error, described in topic or error with blurred background image? And which version of theme you are using now, qt5 or qt6?

The error mentioned in the issue description. I am using the qt6 version.

[stepanzubkov]

For me, on NixOS, qt6 theme works well. I think you are using sddm-greeter compiled with qt5. What is the output of command sddm-greeter --version for you?

[GaetanLepage]

Hmm, weird. I have not specified anything special regarding sddm. Here is the relevant config.

❯ sddm-greeter --version
[00:28:19.395] (II) GREETER: High-DPI autoscaling Enabled
sddm-greeter 

[GaetanLepage]

Hmm, weird. I have not specified anything special regarding sddm. Here is the relevant config.

Am I doing anything wrong ? Are you on nixos-unstable as well ?

You should try qt5 theme

[GaetanLepage]

You should try qt5 theme

QT5 theme works indeed. I'll keep using that then. Thanks :)
