› Others environments / manual install :

Download the tar archive from openDesktop and extract the content to the theme directory of SDDM :

sudo tar -xzvf ~/Downloads/sddm-THEMENAME.tar.gz -C /usr/share/sddm/themes

This will extract all the files to a new folder "THEMENAME" inside of the themes directory of SDDM.
After that you will have to point SDDM to the new theme by editing its config files :

vi /etc/sddm.conf.d/sddm.conf

In the

[Theme]

section set

Current=THEMENAME

. For a more detailed description please refer to the Arch Wiki.
Note that, depending on your system setup, a duplicate configuration may exist in

/etc/sddm.conf

. Usually this takes preference so you want to set the above line in this file if you have it.

Last changelog:

Version 0.26 years ago

> Update Keyboard layout / Dropdown menu :
There is a "cosmetic" bug with sddm who use xcb API to list the keymaps :
On the initial loading, the keyboard layout dropdown menu shows "English (US)" only (your true keyboard layout is selected but this may be visual wrong).
As soon as any key is pressed then XCB_XKB_NEW_KEYBOARD_NOTIFY event will be issued and then it will return correct layout.
This "bug" is Independent of the theme but for better "deal with that", i have update the theme code and the selected keyboard layout real name is now automatic returned after a first key is pressed which was not the case before.
See : https://github.com/sddm/sddm/issues/202

> Color Background :
Better package integration for sddm_kcm install.
Fix the initial installation via system setting who wrongly alter the default background color with wallpaper image.
