#### Syncing themes
To sync wallpapers, colors, and other settings from the logged in user, you can add your user to the `greeter` group and symlink the shell configurations.
#### Syncing themes (Optional)
To sync your wallpaper and theme with the greeter login screen:
```bash
sudo usermod -aG greeter <username>
# LOGOUT and LOGIN after adding user to group
ln -sf ~/.config/DankMaterialShell/settings.json /var/cache/dms-greeter/settings.json
ln -sf ~/.local/state/DankMaterialShell/session.json /var/cache/dms-greeter/session.json
ln -sf ~/.cache/quickshell/dankshell/dms-colors.json /var/cache/dms-greeter/colors.json
dms-greeter-sync
```
Then logout/login for changes to take effect. Your wallpaper and theme will appear on the greeter!
<details>
<summary>What does dms-greeter-sync do?</summary>
The `dms-greeter-sync` helper automatically:
- Adds you to the greeter group
- Sets minimal ACL permissions on parent directories (traverse only)
- Sets group ownership on your DMS config directories
- Creates symlinks to share your theme files with the greeter
This uses standard Linux ACLs (Access Control Lists) - the same security model used by GNOME, KDE, and systemd. The greeter user only gets traverse permission through your directories and can only read the specific theme files you share.
</details>
<details>
<summary>Manual theme syncing (advanced)</summary>
If you prefer to set up theme syncing manually:
```bash
# Add yourself to greeter group
sudo usermod -aG greeter <username>
# Set ACLs to allow greeter to traverse your directories
setfacl -m u:greeter:x ~ ~/.config ~/.local ~/.cache ~/.local/state
# Set group ownership on config directories
sudo chgrp -R greeter ~/.config/DankMaterialShell
sudo chgrp -R greeter ~/.local/state/DankMaterialShell
sudo chgrp -R greeter ~/.cache/quickshell
sudo chmod -R g+rX ~/.config/DankMaterialShell ~/.local/state/DankMaterialShell ~/.cache/quickshell
# Create symlinks
sudo ln -sf ~/.config/DankMaterialShell/settings.json /var/cache/dms-greeter/settings.json
sudo ln -sf ~/.local/state/DankMaterialShell/session.json /var/cache/dms-greeter/session.json
sudo ln -sf ~/.cache/quickshell/dankshell/dms-colors.json /var/cache/dms-greeter/colors.json
# Logout and login for group membership to take effect
```

### Fedora / RHEL / Rocky / Alma
Install from COPR or build the RPM:
```bash
# From COPR (when available)
sudo dnf copr enable avenge/dms
sudo dnf install dms-greeter
# Or build locally
cd /path/to/DankMaterialShell
rpkg local
sudo rpm -ivh x86_64/dms-greeter-*.rpm
```
The package automatically:
- Creates the greeter user
- Sets up directories and permissions
- Configures greetd with auto-detected compositor
- Applies SELinux contexts
Then disable existing display manager and enable greetd:
```bash
sudo systemctl disable gdm sddm lightdm
sudo systemctl enable greetd
```
**Optional:** Sync your theme with the greeter:
```bash
dms-greeter-sync
```
Then logout/login to see your wallpaper on the greeter!

#### Personalization
Wallpapers and themes and weather and clock formats and things are a TODO on the documentation, but it's configured exactly the same as dms.
The greeter can be personalized with wallpapers, themes, weather, clock formats, and more - configured exactly the same as dms.
You can synchronize those configurations with a specific user if you want greeter settings to always mirror the shell.
**Easiest method:** Run `dms-greeter-sync` to automatically sync your DMS theme with the greeter.
The greeter uses the `dms-greeter` group for file access permissions, so ensure your user and the greeter user are both members of this group.
**Manual method:** You can manually synchronize configurations if you want greeter settings to always mirror your shell:
```bash
# For core settings (theme, clock formats, etc)
# Add yourself to the greeter group
sudo usermod -aG greeter $USER
# Set ACLs to allow greeter user to traverse your home directory
setfacl -m u:greeter:x ~ ~/.config ~/.local ~/.cache ~/.local/state
# Set group permissions on DMS directories
sudo chgrp -R greeter ~/.config/DankMaterialShell ~/.local/state/DankMaterialShell ~/.cache/quickshell
sudo chmod -R g+rX ~/.config/DankMaterialShell ~/.local/state/DankMaterialShell ~/.cache/quickshell
# Create symlinks for theme files
sudo ln -sf ~/.config/DankMaterialShell/settings.json /var/cache/dms-greeter/settings.json
# For state (mainly you would configure wallpaper in this file)
sudo ln -sf ~/.local/state/DankMaterialShell/session.json /var/cache/dms-greeter/session.json
# For wallpaper based theming
sudo ln -sf ~/.cache/quickshell/dankshell/dms-colors.json /var/cache/dms-greeter/dms-colors.json
sudo ln -sf ~/.cache/quickshell/dankshell/dms-colors.json /var/cache/dms-greeter/colors.json
# Logout and login for group membership to take effect
```
You can override the configuration path with the `DMS_GREET_CFG_DIR` environment variable or the `--cache-dir` flag when using `dms-greeter`. The default is `/var/cache/dms-greeter`.
**Advanced:** You can override the configuration path with the `DMS_GREET_CFG_DIR` environment variable or the `--cache-dir` flag when using `dms-greeter`. The default is `/var/cache/dms-greeter`.
The cache directory should be owned by `greeter:greeter` with `770` permissions.
