+# Linux desktop build and runtime
+
+The Linux desktop entry, installed icon, and GTK application must all use the
+same application ID: `com.mithqal.ai`.
+
+## Ubuntu and Debian build dependencies
+
+Install Flutter's Linux desktop toolchain and the native secret-storage
+development library:
+
+```sh
+sudo apt-get update
+sudo apt-get install -y \
+  clang cmake ninja-build pkg-config libgtk-3-dev libstdc++-12-dev \
+  libsecret-1-dev libsecret-1-0
+```
+
+Then check the host and build the release bundle:
+
+```sh
+flutter doctor -v
+flutter devices
+flutter pub get
+flutter build linux --release
+```
+
+The executable bundle is produced at
+`build/linux/x64/release/bundle/`. Distribute the complete bundle and verify
+its native runtime dependencies on the target distribution, for example with
+`ldd build/linux/x64/release/bundle/flutter_app`.
+
+## Secure session storage
+
+`flutter_secure_storage` uses Libsecret on Linux. Build machines need
+`libsecret-1-dev`; packaged applications need the runtime library
+`libsecret-1-0`. The desktop session must also provide D-Bus and an unlocked
+Secret Service keyring, commonly GNOME Keyring or KDE Wallet. Run the
+application in an interactive desktop session to verify login, token
+persistence after restart, and logout deletion. Do not treat a successful
+Linux build as proof that secure storage works: headless sessions and CI may
+have no unlocked keyring.
