-The OpenCV Package in Ubuntu use the GTK Backend for the preview window. This will cause freezes of the UI, because i use Qt threads in my code. The Arch Linux OpenCV library was compiled with QT (see `python3 -c "import cv2; print(cv2.getBuildInformation())"` output) so no problem here. To use the Application on Ubuntu you have to compile `OpenCV + OpenCV contrib` with `-D WITH_QT=ON` flag from source. Or simply use [miniconda](https://docs.conda.io/en/latest/miniconda.html). They include OpenCV compiled with Qt support.

-**NOTE:** I have also test this setup on Ubuntu 21.04 with Wayland desktop. You can use the setup instructions from Ubuntu 20.04 LTS. The application work with XWayland on the Wayland desktop!

-### Miniconda

-After you have setup [miniconda](https://docs.conda.io/en/latest/miniconda.html) on your machine simply type the following commands to use Python-Funscript-Editor:
-
-```bash
-sudo apt install -y make git gcc g++ cmake libmpv-dev libatlas-base-dev
-git clone https://github.com/michael-mueller-git/Python-Funscript-Editor.git
-cd Python-Funscript-Editor
-conda env create -f environment_ubuntu.yaml
-```
-
-On some distributions e.g. Ubuntu 20.04 LTS, the FFmpeg package does not contain the required `v360` filter. Therefore you can download a static linked FFmpeg package for this application with `bash download_ffmpeg.sh` from project root directory. (Perform this step if you are not sure if your FFmpeg version is sufficient!). The latest ffmpeg downloaded via `download_ffmpeg.sh` break current MTFG. Therefore you should copy the ffmpeg executable from `./assets` to `./funscript_editor/data` for now.
-
-Ubuntu user can alternatively use the `savoury1` ppa:
-
-```bash
-sudo add-apt-repository ppa:savoury1/ffmpeg4
-sudo apt install -y ffmpeg
-
-```
-
-Now you can run the program direct from source code with:
-
-```bash
-conda activate funscript-editor
-python3 funscript-editor.py
-```
-
-By default the latest code is used which may contain bugs. So you maybe want to switch to the latest release version with `` git checkout $(git describe --tags `git rev-list --tags --max-count=1`)``.
-
-You can always update the application to the latest version with `git checkout main && git pull` inside the repository directory.

-## Arch Linux and Arch-Based Distributions
-
-My development platform is Arch Linux. The code should run therefore without problems. When installing the dependencies, make sure you install the following packages from the repositories, as the wrapper will have problems if the versions differ from the pip packages and the local C, C++ libraries.
-
-```bash
-sudo pacman -Syu  # this ensure the new libraries will be compatible
-sudo pacman -Sy python-opencv python-pyqt5
-```
-
-All other required python packages can be installed from pip.

-The latest ffmpeg break current MTFG. Therefore you should copy the ffmpeg executable from `./assets` to `./funscript_editor/data` for now!!
+To run the application on Linux you need the [nix package manager](https://nixos.org/download.html) with experimental [`flakes` feature enabled](https://github.com/mschwaig/howto-install-nix-with-flake-support).

@@ -80,16 +33,6 @@ Limitation of the flatpak application:
 - Flatpak need non-privileged user namespaces enabled (`sysctl kernel.unprivileged_userns_clone=1'`).
 - The System-Theme is not applied to the application. The problem is that my recipe use conda packages which isolates the python packages inside the flatpak sandbox and we have no access to the system theme. To fix this we have to build all python packages in the flatpak recipe from source and include the system theme inside the flatpak.
