Freshly Installed Manjaro KDE Plasma throws SDDM error

Manjaro devlopers do not fix upstream bugs.

Manjaro Linux provides upstream Plasma - and granted - there is a holdback for Plasma 6.1 until Nvidia stabilizes - which may happen soon.

Other than that - it’s on your table.

So the conclusion of your topic title is

  • No - Manjaro does not throw SDDM error on a fresh install.
  • The error emerges when you install an unsupported theme.

What you were actually asking is how to be sure you are installing a theme meant for Plasma 6.(x). Correct?

There is no shortcut – You have to pay attention to the information provided with the theme before you install it.

If the theme information does not specifically state that it’s for Plasma 6 (or above) then simply do not install it. Instead, keep searching until you find a compatible theme that appeals to you.

There are not many Plasma 6 compatible themes in the wild. I would normally recommend using the default Breeze theme until random theme makers eventually update their themes, or create some specifically for Plasma 6.x.

One theme that you might like; and that’s known to be compatible;
is a theme called Carl:

There are also some Plasma6 Global Themes that might also interest you:

Tip: Notice the theme names all have a 6 at the end – this usually suggests they are meant for Plasma 6.

Happy hunting.

Since there are old Themes for Plasma 5 version and themes which are to probably to new for Plasma 6.1 (if this is really the culprit for you issue…), i recommend to click on “show most recent first” and scroll a little bid down, then i found a Theme which was 4 month old like this one:

Which shows a creation date at middle february… which means there was just the Plasma 6 release… 02/2024 till 06/2024 should be good to install.

I did review this theme and I have to say, its really unique you know. I’ll save these aswell!
Thank you so much @Kobold

Plasma usually works OOB with the default global theme.

Manjaro provides a branded version of the default Breeze theme - so it also works OOB.

Because themes is not just a bunch of colors and svgs - it is also QML (javascript templates) so some components may not work well if at all if it is too old or poorly maintained.

To see which global themes currently with KDE store and made specifically for Plasma 6

My preferred theme - is also a custom theme - and the current version of the greeter theme throws errors too. I have packaged it for my own use - so I still have a functional greeter.
