While not generally recommended, certain legacy environments specifically those with older hardware or outdated Linux distributions may require the deactivation of the standard seccomp profile to get containerized desktop software to run. This can be achieved by utilizing the `--security-opt seccomp=unconfined` parameter. It is critical to use this option only when absolutely necessary as it disables a key security layer of Docker, elevating the potential for container escape vulnerabilities.
### Hardware Acceleration & The Move to Wayland
We are currently transitioning our desktop containers from X11 to Wayland. While X11 is still the default, we strongly encourage users to test the new Wayland mode.
**Important:** GPU acceleration support for X11 is being deprecated. Future development for hardware acceleration will focus entirely on the Wayland stack.
To enable Wayland mode, set the following environment variable:
* `-e PIXELFLUX_WAYLAND=true`
**Why use Wayland?**
* **Zero Copy Encoding:** When configured correctly with a GPU, the frame is rendered and encoded on the video card without ever being copied to the system RAM. This drastically lowers CPU usage and latency.
* **Modern Stack:** Single-application containers utilize **Labwc** (replacing Openbox) and full desktop containers use **KDE Plasma Wayland**, providing a more modern and secure compositing environment while retaining the same user experience.
#### GPU Configuration
To use hardware acceleration in Wayland mode, we distinguish between the card used for **Rendering** (3D apps/Desktops) and **Encoding** (Video Stream).
**Configuration Variables:**
* `DRINODE`: The path to the GPU used for **Rendering** (EGL).
* `DRI_NODE`: The path to the GPU used for **Encoding** (VAAPI/NVENC).
If both variables point to the same device, the container will automatically enable **Zero Copy** encoding, significantly reducing CPU usage and latency.
##### Intel & AMD (Open Source Drivers)
For Intel and AMD GPUs.
```yaml
devices:
- /dev/dri:/dev/dri
environment:
- PIXELFLUX_WAYLAND=true
# Optional: Specify device if multiple exist (IE: /dev/dri/renderD129)
- DRINODE=/dev/dri/renderD128
- DRI_NODE=/dev/dri/renderD128
```

???+ note "Click to expand: Legacy X11 Resolution & Acceleration"
**Note:** This section applies only if you are **NOT** using `PIXELFLUX_WAYLAND=true`.
When using 3d acceleration via Nvidia DRM or DRI3 in X11 mode, it is important to clamp the virtual display to a reasonable max resolution to avoid memory exhaustion or poor performance.
* `-e MAX_RESOLUTION=3840x2160`
This will set the total virtual framebuffer to 4K. By default, the virtual monitor is 16K. If you have performance issues in an accelerated X11 session, try clamping the resolution to 1080p and work up from there:
```
-e SELKIES_MANUAL_WIDTH=1920
-e SELKIES_MANUAL_HEIGHT=1080
-e MAX_RESOLUTION=1920x1080

### All GPU Acceleration - use sane resolutions
When using 3d acceleration via Nvidia DRM or DRI3 it is important to clamp the virtual display to a reasonable max resolution. This can be achieved with the environment setting:
* `-e MAX_RESOLUTION=3840x2160`
This will set the total virtual framebuffer to 4K, you can also set a manual resolution to achieve this.
By default the virtual monitor in the session is 16K to support large monitors and dual display configurations. Leaving it this large has no impact on CPU based performance but costs GPU memory usage and memory bandwidth when leveraging one for acceleration. If you have performance issues in an accelerated session, try clamping the resolution to 1080p and work up from there:
```
-e SELKIES_MANUAL_WIDTH=1920
-e SELKIES_MANUAL_HEIGHT=1080
-e MAX_RESOLUTION=1920x1080
```
### DRI3 GPU Acceleration
For accelerated apps or games, render devices can be mounted into the container and leveraged by applications using:
`--device /dev/dri:/dev/dri`
This feature only supports **Open Source** GPU drivers:
| Driver | Description |
| :----: | --- |
| Intel | i965 and i915 drivers for Intel iGPU chipsets |
| AMD | AMDGPU, Radeon, and ATI drivers for AMD dedicated or APU chipsets |
| NVIDIA | nouveau2 drivers only, closed source NVIDIA drivers lack DRI3 support |
The `DRINODE` environment variable can be used to point to a specific GPU.
DRI3 will work on aarch64 given the correct drivers are installed inside the container for your chipset.

???+ note "Click to expand: Hardening Options"
##### Meta Variables
These variables can be used to lock down the desktop environment for single-application use cases or to restrict user capabilities.
| Variable | Description |
| :----: | --- |
| **`HARDEN_DESKTOP`** | Enables `DISABLE_OPEN_TOOLS`, `DISABLE_SUDO`, and `DISABLE_TERMINALS`. Also sets related Selkies UI settings (`SELKIES_FILE_TRANSFERS`, `SELKIES_COMMAND_ENABLED`, `SELKIES_UI_SIDEBAR_SHOW_FILES`, `SELKIES_UI_SIDEBAR_SHOW_APPS`) if they are not explicitly set by the user. |
| **`HARDEN_OPENBOX`** | Enables `DISABLE_CLOSE_BUTTON`, `DISABLE_MOUSE_BUTTONS`, and `HARDEN_KEYBINDS`. It also flags `RESTART_APP` if not set by the user, ensuring the primary application is automatically restarted if closed. |
**Individual Hardening Variables:**
| Variable | Description |
| :--- | --- |
| **`DISABLE_OPEN_TOOLS`** | If true, disables `xdg-open` and `exo-open` binaries by removing their execute permissions. |
| **`DISABLE_SUDO`** | If true, disables the `sudo` command by removing its execute permissions and invalidating the passwordless sudo configuration. |
| **`DISABLE_TERMINALS`** | If true, disables common terminal emulators by removing their execute permissions and hiding them from the Openbox right-click menu. |
| **`DISABLE_CLOSE_BUTTON`** | If true, removes the close button from window title bars in the Openbox window manager. |
| **`DISABLE_MOUSE_BUTTONS`** | If true, disables the right-click and middle-click context menus and actions within the Openbox window manager. |
| **`HARDEN_KEYBINDS`** | If true, disables default Openbox keybinds that can bypass other hardening options (e.g., `Alt+F4` to close windows, `Alt+Escape` to show the root menu). |
| **`RESTART_APP`** | If true, enables a watchdog service that automatically restarts the main application if it is closed. The user's autostart script is made read-only and root owned to prevent tampering. |
These variables act as presets, enabling multiple hardening options at once. Individual options can still be set to override the preset.

#### Selkies application settings
Using environment variables every facet of the application can be configured.
##### Booleans and Locking
Boolean settings accept `true` or `false`. You can also prevent the user from changing a boolean setting in the UI by appending `|locked`. The UI toggle for this setting will be hidden.
* **Example**: To force CPU encoding on and prevent the user from disabling it:
```bash
-e SELKIES_USE_CPU="true|locked"
```
##### Enums and Lists
These settings accept a comma-separated list of values. Their behavior depends on the number of items provided:
* **Multiple Values**: The first item in the list becomes the default selection, and all items in the list become the available options in the UI dropdown.
* **Single Value**: The provided value becomes the default, and the UI dropdown is hidden because the choice is locked.
* **Example**: Force the encoder to be `jpeg` with no other options available to the user:
```bash
-e SELKIES_ENCODER="jpeg"
```
##### Ranges
Range settings define a minimum and maximum for a value (e.g., framerate).
* **To set a range**: Use a hyphen-separated `min-max` format. The UI will show a slider.
* **To set a fixed value**: Provide a single number. This will lock the value and hide the UI slider.
* **Example**: Lock the framerate to exactly 60 FPS.
```bash
-e SELKIES_FRAMERATE="60"
```
##### Manual Resolution Mode
The server can be forced to use a single, fixed resolution for all connecting clients. This mode is automatically activated if `SELKIES_MANUAL_WIDTH`, `SELKIES_MANUAL_HEIGHT`, or `SELKIES_IS_MANUAL_RESOLUTION_MODE` is set.
* If `SELKIES_MANUAL_WIDTH` and/or `SELKIES_MANUAL_HEIGHT` are set, the resolution is locked to those values.
* If `SELKIES_IS_MANUAL_RESOLUTION_MODE` is set to `true` without specifying width or height, the resolution defaults to **1024x768**.
* When this mode is active, the client UI for changing resolution is disabled.
