When the target device is disabled, ProcXIGrabDevice returns AlreadyGrabbed directly as the request handler return value. AlreadyGrabbed (1) is a grab status code, not an X error code. The server dispatch loop interprets any non-zero return value as an X protocol error, so the client receives BadRequest (error code 1) instead of a proper XIGrabDevice reply with status=AlreadyGrabbed. And use XIAlreadyGrabbed since this is an XI2 request. It's the same value anyway. This is the same class of bug that was fixed in ProcXIPassiveGrabDevice by commit 'Xi: Fix XIPassiveGrab handling of keycodes > 255' Fix by jumping to the reply path with status=AlreadyGrabbed instead of returning the status code directly.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
