[Rdesktop](http://xrdp.org/) - Containers containing full desktop environments in many popular flavors for Alpine, Ubuntu, Arch, and Fedora accessible via RDP.
We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
Simply pulling `lscr.io/linuxserver/rdesktop:latest` should retrieve the correct image for your arch, but you can also pull specific arch images via tags.
This image provides various versions that are available via tags. Please read the descriptions carefully and exercise caution when using unstable or development tags.
**Unlike our other containers these Desktops are not designed to be upgraded by Docker, you will keep your home directoy but anything you installed system level will be lost if you upgrade an existing container. To keep packages up to date instead use Ubuntu's own apt, Alpine's apk, Fedora's dnf, or Arch's pacman program**
You will need a Remote Desktop client to access this container [Wikipedia List](https://en.wikipedia.org/wiki/Comparison_of_remote_desktop_software), by default it listens on 3389, but you can change that port to whatever you wish on the host side IE `3390:3389`.
The first thing you should do when you login to the container is to change the abc users password by issuing the `passwd` command.
**Modern GUI desktop apps (including some flavors terminals) have issues with the latest Docker and syscall compatibility, you can use Docker with the `--security-opt seccomp=unconfined` setting to allow these syscalls or try [podman](https://podman.io/) as they have updated their codebase to support them**
If you ever lose your password you can always reset it by execing into the container as root:
```
docker exec -it rdesktop passwd abc
```
By default we perform all logic for the abc user and we reccomend using that user only in the container, but new users can be added as long as there is a `startwm.sh` executable script in their home directory.
All of these containers are configured with passwordless sudo, we make no efforts to secure or harden these containers and we do not reccomend ever publishing their ports to the public Internet.
Many desktop application will need access to a GPU to function properly and even some Desktop Environments have compisitor effects that will not function without a GPU. This is not a hard requirement and all base images will function without a video device mounted into the container.
### Intel/ATI/AMD
To leverage hardware acceleration you will need to mount /dev/dri video device inside of the conainer.
```
--device=/dev/dri:/dev/dri
```
We will automatically ensure the abc user inside of the container has the proper permissions to access this device.
### Nvidia
Hardware acceleration users for Nvidia will need to install the container runtime provided by Nvidia on their host, instructions can be found here:
https://github.com/NVIDIA/nvidia-docker
We automatically add the necessary environment variable that will utilise all the features available on a GPU on the host. Once nvidia-docker is installed on your host you will need to re/create the docker container with the nvidia container runtime `--runtime=nvidia` and add an environment variable `-e NVIDIA_VISIBLE_DEVICES=all` (can also be set to a specific gpu's UUID, this can be discovered by running `nvidia-smi --query-gpu=gpu_name,gpu_uuid --format=csv` ). NVIDIA automatically mounts the GPU and drivers from your host into the container.
### Arm Devices
Best effort is made to install tools to allow mounting in /dev/dri on Arm devices. In most cases if /dev/dri exists on the host it should just work. If running a Raspberry Pi 4 be sure to enable `dtoverlay=vc4-fkms-v3d` in your usercfg.txt.
Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.
For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional `-e UMASK=022` setting.
Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up [here](https://en.wikipedia.org/wiki/Umask) before asking for support.
When using volumes (`-v` flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user `PUID` and group `PGID`.

We publish various [Docker Mods](https://github.com/linuxserver/docker-mods) to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
