The relevant part of the layout definition is: { "border": "normal", "floating": "auto_off", "geometry": { "height": 510, "width": 761, "x": 0, "y": 0 }, "name": "IPython", "percent": 0.391100702576112, "swallows": [ { "title": "^IPython$" } ], "type": "con" } I'm starting the application like this: i3-msg "workspace 1; append_layout ${HOME}/.i3/workspace-1.json" emacs & icedove & iceweasel & ipython3 qtconsole & ..and xprop says about the Ipython window: $ xprop [...] WM_NAME(STRING) = "IPython" WM_LOCALE_NAME(STRING) = "en_US.UTF-8" WM_CLASS(STRING) = "", "" WM_HINTS(WM_HINTS): Client accepts input or input focus: True Initial state is Normal State. bitmap id # to use for icon: 0x260000d window id # of group leader: 0x2600007 WM_NORMAL_HINTS(WM_SIZE_HINTS): program specified minimum size: 125 by 109 window gravity: NorthWest WM_CLIENT_MACHINE(STRING) = "nelarikon" WM_COMMAND(STRING) = { } but the window never seems to get placed into its designated position.
