 ## Open the app
 
+**Optional: open at login.** In the installed desktop app, choose **Frame → Open at Login**. It is off by default. When on, a login launch starts in the tray or menu bar if that control is available; click its icon to open the window, or use its **Quit Frame Control** menu item. Closing the window keeps the app in the tray while this option is on. Turn the same menu option off to remove its OS login item. On Linux this creates or removes only Frame Control's own file in `~/.config/autostart/` (or `$XDG_CONFIG_HOME/autostart/`). If the desktop has no working tray, the window opens at login instead. A source checkout does not offer this setting.
+
 - **macOS:** open the `.dmg`, drag **Frame Control** to **Applications**, then
   open it from Applications. For the unsigned-app warning, use the macOS steps
   above. Allow local network access and control of Terminal when prompted.

-Current for Frame Control **v0.4.25**, 25 October 2026. “Real Frame + physical PC” means an actual headset and a non-virtual computer. “VM only” means a Windows virtual machine, sometimes connected to the real Frame. A CI test or a simulated device is **not** a physical hardware test. The date/version column is the last relevant check, not a promise that every new release was retested on that platform. See each link for the exact procedure and limits.
-
-| Feature | Real Frame + physical PC tested | VM only | Untested or limited | Last check and proof |
-|---|---|---|---|---|
-| Windows desktop in the headset | No physical Windows PC test | Windows 11 VM sent a whole desktop to a real Frame; this used an intermediate fix, not the final native DLL | Physical GPU, capture and controller input; individual windows unavailable in bundled DXGI build | 24 Oct, v0.4.10 installer + candidate fix: [VM log](evidence/windows-vm-2026-10-24.md), [PC guide](pc-in-headset.md) |
-| Linux desktop in the headset | No | No | Native Linux PC capture is disabled; lxso2 lacked a desktop portal and PipeWire session. The separate Steam `-pipewire` helper is not Frame Control's PC capture | 24 Oct, v0.4.17: [host audit](evidence/linux-pc-host-lxso2-2026-10-24.md), [Steam helper PR #163](https://github.com/saphid/frame-control/pull/163) |
