Features

• The user will be shown with a Capital Letter regardless of the typed case, this is only a graphical effect
  • You can choose the capitalization through the theme.conf file
• Last logged in user will be used as text placeholder
• Random quotes will be fetched from the Quotes module
  • The Quotes Folder is now simply for reference and to store quotes you may want
• Sound effects play on button switch
• Scales to higher resolutions. If you have a 16:9 instead of a 16:10 monitor, change the height in the sizeHelper in Main.qml from 1200 to 1080

Install (Qt5 theme, read this or cry later)

This thing runs on Qt5. Most systems default to Qt6 now. Skip the deps below and you get a black screen and no explanation, don't say we didn't warn you.

0. Make sure you're actually on SDDM. Newer Plasma (6.6+) ships with Plasma Login Manager by default instead, and it's hardcoded to Breeze, no custom themes allowed. Check what you're running:

systemctl status display-manager

If it says plasmalogin.service instead of sddm.service, install SDDM and switch:

sudo pacman -S --needed sddm
sudo systemctl disable plasmalogin.service
sudo systemctl enable sddm.service

1. Grab the deps (Arch/CachyOS):

sudo pacman -S --needed qt5-graphicaleffects qt5-declarative qt5-quickcontrols2 qt5-svg qt5-multimedia qt5-wayland layer-shell-qt gst-libav gst-plugins-good gst-plugins-bad gst-plugins-ugly

layer-shell-qt only comes Qt6 in your repos? Grab it from AUR instead:

paru -S layer-shell-qt5

2. Clone it in:

cd /usr/share/sddm/themes
git clone https://github.com/1LittleDrag0n/YoRHa-sddm-theme

3. Set it as your theme. Edit /etc/sddm.conf:

[Theme]
Current=YoRHa-sddm-theme

4. Reboot. Done.

Wanna preview it first without breaking your login screen?

sddm-greeter --test-mode --theme /usr/share/sddm/themes/YoRHa-sddm-theme

Use sddm-greeter, NOT sddm-greeter-qt6. This theme's a Qt5 kid, it doesn't know Qt6.

Black Screen? Here's the fix, pick your symptom

• Loads then instantly fallback, no errors → metadata.desktop has QtVersion=6 in it, delete that line
• "module X is not installed" error → missing a Qt5 package, reinstall the deps list above
• Full crash, no window at all, "no Qt platform plugin" → sudo pacman -S --needed qt5-wayland
• You get a cursor but literally nothing else → missing layer-shell-qt (or AUR layer-shell-qt5)
• No errors, everything "works," still black → missing video codecs, sudo pacman -S --needed gst-libav gst-plugins-good gst-plugins-bad gst-plugins-ugly

Still stuck? Check what the greeter itself is screaming about (SDDM's own logs won't show you this):

journalctl -b _COMM=sddm-greeter --no-pager

Font looks off? Theme wants "Moto Sans" font, if you don't have it it just falls back, not a bug, just ugly.
