The purpose of these images is to provide a full featured rdesktop Linux desktop experience for any Linux application or desktop environment. They ship with passwordless sudo to allow easy package installation, testing, and customization. By default they have no logic to mount out anything but the users home directory, meaning on image updates anything outside of `/config` will be lost.
The environment variable `LC_ALL` can be used to start this image in a different language than English simply pass for example to launch the Desktop session in French `LC_ALL=fr_FR.UTF-8`. Some languages like Chinese, Japanese, or Korean will be missing fonts needed to render properly known as cjk fonts, but others may exist and not be installed. We only ensure fonts for Latin characters are present. Fonts can be installed with a mod on startup.
All base images are built for x86_64 and aarch64 platforms.
| Distro | Current Tag |

| Alpine | alpine320 |
| Arch | arch |
| Debian | debianbookworm |

# PRoot Apps
All images include [proot-apps](https://github.com/linuxserver/proot-apps) which allow portable applications to be installed to persistent storage in the user's `$HOME` directory. These applications and their settings will persist upgrades of the base container and can be mounted into different flavors of rdesktop containers. IE if you are running an Alpine based container you will be able to use the same `/config` directory mounted into an Ubuntu based container and retain the same applications and settings as long as they were installed with `proot-apps install`.
A list of linuxserver.io supported applications is located [HERE](https://github.com/linuxserver/proot-apps?tab=readme-ov-file#supported-apps).

## Building images
### Application containers
Included in these base images is a simple [Openbox DE](http://openbox.org/) and the accompanying logic needed to launch a single application. Lets look at the bare minimum needed to create an application container starting with a Dockerfile:
```
FROM ghcr.io/linuxserver/baseimage-rdesktop:alpine320
RUN apk add --no-cache firefox
COPY /root /
```
And we can define the application to start using:
```
mkdir -p root/defaults
echo "firefox" > root/defaults/autostart
```
Resulting in a folder that looks like this:
```
├── Dockerfile
└── root
└── defaults
└── autostart
```
Now build and test:
```
docker build -t firefox .
docker run --rm -it -p 3389:3389 firefox bash
```
On rdp port 3389 you will be presented with a fullscreen firefox window.
This similar setup can be used to embed any Linux Desktop application in an rdp accesible container.
**If building images it is important to note that many application will not work inside of Docker without `--security-opt seccomp=unconfined`, they may have launch flags to not use syscalls blocked by Docker like with chromium based applications and `--no-sandbox`. In general do not expect every application will simply work like a native Linux installation without some modifications**
#### In container application launching
Also included in the init logic is the ability to define application launchers. As the user has the ability to close the application or if they want to open multiple instances of it this can be useful. Here is an example of a menu definition file for Firefox:
Simply create this file and add it to your defaults folder as `menu.xml`:
```
├── Dockerfile
└── root
└── defaults
└── autostart
└── menu.xml
```
This allows users to right click the desktop background to launch the application.
### Full Desktop environments
When building an application container we are leveraging the Openbox DE to handle window management, but it is also possible to completely replace the DE that is launched on container init using the `startwm.sh` script, located again in defaults:
```
├── Dockerfile
└── root
└── defaults
└── startwm.sh
```
If included in the build logic it will be launched in place of Openbox. Examples for this kind of configuration can be found in our [rdesktop repository](https://github.com/linuxserver/docker-rdesktop)
## Open Source 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 |
