In order to run X11 applications from a Wayland session of VSCodium, close VSCodium and run this command:

flatpak override --user --nosocket=fallback-x11 --socket=x11 com.vscodium.codium

Note: Wayland applications are unaffected by this change and run normally.

Note that VSCodium is granted full access to your host directories (but at certain grade is still sandboxed).

You can use flatpak override to locally adjust this if you prefer a more hardened sandbox for VSCodium file system access:

flatpak override --user com.vscodium.codium --nofilesystem=host

Now manually grant accesss to the folder(s) you want to work in

flatpak override --user com.vscodium.codium --filesystem=~/src

Remember: this version is running inside a container and is therefore not able to access SDKs on your host system!

$ flatpak-spawn --host <COMMAND>

or

$ host-spawn <COMMAND>

• Most users seem to report a better experience with host-spawn.

Note that this runs the COMMAND without any further host-side confirmation. If you want to prevent such full host access from inside the sandbox, you can use flatpak override as follows:

flatpak override --user com.vscodium.codium --no-talk-name=org.freedesktop.Flatpak

Since there are many ways to achieve this, the best way is to use vsix-manager.

To make the Integrated Terminal automatically use the host system's shell, you can add one of the following configurations for flatpak-spawn or host-spawn to the settings of vscodium:

flatpak-spawn

  {
    "terminal.integrated.defaultProfile.linux": "bash",
    "terminal.integrated.profiles.linux": {
      "bash": {
        "path": "/usr/bin/flatpak-spawn",
        "args": ["--host", "--env=TERM=xterm-256color", "bash"],
        "icon": "terminal-bash",
        "overrideName": true
      }
    },
  }

host-spawn

  {
    "terminal.integrated.defaultProfile.linux": "bash",
    "terminal.integrated.profiles.linux": {
      "bash": {
        "path": "/app/bin/host-spawn",
        "args": ["bash"],
        "icon": "terminal-bash",
        "overrideName": true
      }
    },
  }

• You can change bash to any terminal you are using: zsh, fish, sh.
• overrideName allows for the 'name' (or whatever you set it to) of the shell you're using to appear (e.g. normally zsh, fish, sh).

This flatpak provides a standard development environment (gcc, python, etc). To see what's available:

$ flatpak run --command=sh com.vscodium.codium
$ ls /usr/bin (shared runtime)
$ ls /app/bin (bundled with this flatpak)

To get support for additional languages, you have to install SDK extensions, e.g.

$ flatpak install flathub org.freedesktop.Sdk.Extension.dotnet
$ flatpak install flathub org.freedesktop.Sdk.Extension.golang
$ FLATPAK_ENABLE_SDK_EXT=dotnet,golang flatpak run com.vscodium.codium

You can use a GUI tool like Flatseal or the following commands to check and adjust the overrides:

$ flatpak override --user --show com.vscodium.codium # shows existing overrides
$ flatpak override --user --env FLATPAK_ENABLE_SDK_EXT=node22 com.vscodium.codium

Note that VSCodium shows no error when an extension requested via FLATPAK_ENABLE_SDK_EXT does not exist. Make sure to install it properly.

Use

$ flatpak search org.freedesktop.Sdk.Extension

to find others.

If you want to run codium /path/to/file from the host terminal just add this to your shell's rc file

$ alias codium="flatpak run com.vscodium.codium "

then reload sources, now you could try:

$ codium /path/to/
# or
$ FLATPAK_ENABLE_SDK_EXT=dotnet,golang codium /path/to/

To use Git LFS with VSCodium's integrated Git support, you will need the com.visualstudio.code.tool.git-lfs addon.

$ flatpak install flathub com.visualstudio.code.tool.git-lfs

You might need to reinstall the Git LFS hooks in each repo with git lfs install.

• armhf/armv7 builds have their particular branch named armv7 and will be deprecated on 2021 due to the org.freedesktop.Sdk versions >= 20.08 disable armv7 builds. You can follow the discussion here.
• This particular branch is based on org.freedesktop.Sdk == 19.08 that be supported until 2021, you can read more about it here.
