Duplicate Breeze themes in SDDM configuration

[Kenneth Hanson]

In the system settings menu, on the page "Login Screen (SDDM)" there are two themes listed as Breeze, which appear to be completely identical.

I've noticed this in the past, but am reporting it now since it occurs even in a fresh install of Kubuntu 20.04.

In the past, I sometimes deleted one of the two themes by clicking the "Remove" button, but it would come back after a while.

It still present in Kubuntu 21.04/KDE 5.21.4. According to this bug [ https://bugs.kde.org/show_bug.cgi?id=436250 ] it's a Kubuntu packaging issue.

Confirmed on Development Branch (II to become 21.10).

Reverting the fix for now. We need the alternatives so that other flavours can configure their defaults.

Today the SDDM theme was reverted to the fallback one. When I went to SDDM settings, both themes were unselected.

I see this too. An element of nastiness is that it pushes people to try to remove the duplicate theme, but attempting to do so removes both.

Temporary workaround that helped me to get rid of the duplicate theme entries:

1. Delete the symlink /usr/share/themes/sddm/ubuntu-theme
2. In Systemsettings, go to the login screen configuration page, where now only one Breeze entry should be displayed. Click on that entry to select it, and choose "Apply". (This step is important because otherwise you may be greeted with some strange looking non-KDE fallback theme of sddm the next time you log in.)
3. If you had set a custom wallpaper for the SDDM Breeze theme before or changed other settings, you may need to apply them again.

This should work until when the sddm-theme-breeze package gets updated the next time. In this case, you have to repeat the steps above.
