This post comes from my private notes, so it could be some data is missing. Please, let me know and I will add it to the post.
It all started because MounRiver Studio 2, based on vscode (Visual Studio Code), stopped working after upgrading from Fedora 41 to 42. I find the procedure described above has several advantagesn:
- Allows running MounRiver Studio 2 in any Linux distro
- Prevents pollution of you system by encapsulating all packages needed within a container.
Everything works, including the USB debugger. My notes start below, let me know if this was useful!
Epic adventure to make “Mounriver Studio 2 V210” (MRS2) based on vscode work on #Fedora 42.
Background: After updating to Fedora 42 from Fedora 41, MRS stopped working because of some incompatibility. I tested that running Fedora 41 in a VM machine, MRS2 ran without problems.
The first workaround was to work using the Windows version of MRS2 in wine, but it was a bit slow. This would have been the easiest solution.
podman (or docker!) can be used to run the application within a container locally, emulating Fedora 41, which it was kwnon to work before the update. This has the advantage of being much faster and efficient than running the windows version in Wine or a full virtual box emulation with Gnome Boxes.
Steps taken to make it work:
Downloaded “MounRiverStudio_Linux_X64_V210.tar.xz” and extracted it in ~/home/Downloads/MRS2 such that the folders beforeinstall and MRS-linux-x64 are in the MRS2 folder
Created a Dockerfile inside MRS2 that pulls a Fedora 41 image, and installs gtk3, xorg and other dependencies needed by MRS2. It also includes some lines for stability and for permission and user management. It also runs the start.sh file within the folder beforeinstall automatically, as part of the MRS2 installation procedure:
FROM fedora:41
# Install all dependencies

echo "export QT_X11_NO_MITSHM=1" >> /home/mrsuser/.bashrc && \
mkdir -p /tmp/runtime-mrsuser && \
chown mrsuser:mrsuser /tmp/runtime-mrsuser
# Copy beforeinstall directory
COPY beforeinstall /beforeinstall
COPY MRS-linux-x64 /MRS-linux-x64
# Run the setup script
RUN cd /beforeinstall && chmod +x start.sh && ./start.shRun podman build -t mrs2-image -f Dockerfile . to create the docker/podman image mrs2-image in our system
Enable X11 forwarding in console: xhost +local:
Run the image with the following command:
podman run -it --replace --name mrs2 \
-v ~/Downloads/MRS2/mrs2_home:/home/mrsuser:Z \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-v /run/user/$(id -u):/run/user/$(id -u) \
--device /dev/dri \
--device /dev/usb \
--device /dev/bus/usb \

--userns=keep-id \
--memory=4g \
--cpus=4 \
--shm-size=256m \
-e DISPLAY=$DISPLAY \
-e XDG_RUNTIME_DIR=/tmp/runtime-mrsuser \
-e QT_QPA_PLATFORM=xcb \
-e QT_X11_NO_MITSHM=1 \
-e QT_AUTO_SCREEN_SCALE_FACTOR=0 \
-e GDK_BACKEND=x11 \
mrs2-image /bin/bash -c "/MRS-linux-x64/mounriver-studio\ 2"After this, it is possible to add a the command above + the xhost +local: command in to a single batch file (.sh) and create a desktop icon so that such a batch file is called.
