+# Session Switch
+
+An OpenGamepadUI plugin that adds a **Switch to Steam** button to the power
+menu so OpenGamepadUI can return to Steam game mode.
+
+OpenGamepadUI's built-in ChimeraOS platform support adds a "Switch to Desktop"
+button but has no way to get back to Steam game mode once you leave it. This
+plugin adds the missing round-trip button.
+
+## Features
+
+- Adds a **Switch to Steam** button to the power menu, right above the exit
+  button.
+- Returns to the session that was active before OpenGamepadUI took over, so
+  your autologin configuration is left untouched.
+- Restarts InputPlumber before switching so the gamepad is not left in an
+  exclusive (blocked) state for Steam.
+- No configuration required.
+
+## Requirements
+
+- ChimeraOS or SteamOS with OpenGamepadUI running as an exclusive session.
+- Godot 4.4.x on the build machine (the plugin bytecode must match the Godot
+  version embedded in the OpenGamepadUI release you are targeting).
+
+## Installation
+
+Download the plugin zip and place it in the plugins directory
+(`~/.local/share/opengamepadui/plugins`), or build it yourself:
+
+```sh
+make dist
+```
+
+Then restart OpenGamepadUI. The **Switch to Steam** button appears in the
+power menu.
+
+## How it works
+
+- The plugin only activates when the OS session switcher
+  (`/usr/lib/os-session-select`) is present. On other systems the button is
+  never added.
+- Pressing **Switch to Steam** runs
+  `os-session-select <return-session>`, where `<return-session>` is the value
+  ChimeraOS recorded in `~/.config/chimeraos-session-return` before
+  OpenGamepadUI took over (falling back to `gamescope-session-steam-plus`).
+- Before switching, it runs `sudo -n systemctl restart inputplumber`.
+  ChimeraOS's default sudoers grants passwordless access to exactly this
+  command, so the switch stays non-interactive. If passwordless sudo for
+  `systemctl restart inputplumber` is not configured on your system, the
+  restart is skipped with a warning and the switch still proceeds.
+
+## Compatibility
+
+Tested with OpenGamepadUI v0.40.4 on ChimeraOS. The plugin pins to the
+OpenGamepadUI tag it is built against (`OPENGAMEPAD_UI_TAG` in the Makefile)
+so the compiled plugin bytecode always matches the running OpenGamepadUI
+version.
