# Spacium
This custom **Bazzite** image is based on `bazzite-gnome` and
`bazzite-gnome-nvidia-open`. It includes **Dank Material Shell** and **niri**
along with all of the recommended extras for Dank Linux.
My goal with this image is to offer a vanilla DMS/niri experience with gaming
capabilities (via Bazzite). I have added **ghostty** as the default termianl
along with tools to allow developers to create their own DMS plugins.
Feel free to suggest additional software - or just fork this repo and do
whatever you like.
To switch, run one of the following commands from a terminal in any Universal
Blue or Fedora Atomic based install. The first is based on `bazzite-gnome`:
```
sudo bootc switch ghcr.io/irunatbullets/spacium
```
And this image is based on `bazzite-gnome-nvidia-open`:
```
sudo bootc switch ghcr.io/irunatbullets/spacium-nvidia
```
**Important Note:** After switching to this image the login will backup any
existing niri configutation and replace it with standard dms niri configs.
Updates will not retrigger this event.
## What my selection of additional applications achieve
- **ghostty** - nothing, I just switched to it when I started using dms.
- **bluetui** - an application for configuring multiple Bluetooth receivers.
## Known issues and workarounds
### How do I change the dms greeter's background?!
To enable background image syncing with the dms greeter, run the
following from your terminal and follow the steps:
```
dms greeter sync
```
I would like to automate this in future but I'm simply not smart or patient
enough to do it at the moment.
### Matugen isn't themeing my flatpak apps!
Matugen can theme flatpaks by running the following (restart any running apps):
```
sudo flatpak override \
--filesystem=xdg-config/gtk-3.0:rw \
--filesystem=xdg-config/gtkrc-2.0:rw \
--filesystem=xdg-config/gtk-4.0:rw \
--filesystem=xdg-config/gtkrc:rw
```
### The capslock indicator widget doesn't work!
You have to add yourself to the `input` group like this, and then reboot.
```
ujust add-user-to-input-group
```
