The same happens if I change the split commands like so: `exec i3-msg layout splith`, etc. Could somebody please explaing what I'm doing wrong and how I should correct it?

The problem lies elsewhere. There are two problems with that approach: 1. On a empty workspace there is no container on which `layout splith` or `splith` would work. 2. `exec` does not return only after the program has fully started or at least has a window, but returns immediatelly after startup has initalized. The solution to the first problem is to create the first window, before changing the layout to `splith`. The second problem is a bit more tricky. You could probably use i3 IPC and register to to [window events](http://i3wm.org/docs/ipc.html#_window_event). An easy (but not reliable in every case) solution could be an external script: #!/bin/sh i3-msg 'exec pcmanfm' sleep .5 i3-msg 'layout splith; exec pcmanfm' sleep .5 i3-msg 'focus parent; layout splitv; exec terminal' The duration of the sleeps will of course depend on the program you start. Safe this script, for example as 'startup.sh', make it executable and bind it to your shortcut: bindsym $mod+F1 exec --no-startup-id /path/to/startup.sh Mon, 25 Nov 2013 21:27:23 +0000https://faq.i3wm.org/question/2966/what-is-wrong-in-this-use-of-focus-parent/?answer=2973#post-id-2973Comment by geo909 for Your usage of <code>focus parent</code> is correct.

Still doesn't work.. I accepted the answer though as it seems that the method is working for you. I also started trying vifm, so for the moment I won't look further into this, I think..

As for the script not working, I tested it with xclock and xlogo. I now testet with pcmanfm and had to raise the sleep to one second to work reliably. If you start `pcmanfm -d`, a daemon is started and subsequent `pcmanfm` start only client, reducing "time to window".Thu, 28 Nov 2013 10:16:41 +0000https://faq.i3wm.org/question/2966/what-is-wrong-in-this-use-of-focus-parent/?comment=2996#comment-2996Comment by geo909 for Your usage of <code>focus parent</code> is correct.

Unfortunately your script doesn't work. It opens the three programs in a vertical split. I increased the sleep times, but it's still the same. In any case, I think it makes more sense to switch to a dual panel file manager with terminal in handy, like emelfm2..Wed, 27 Nov 2013 12:38:41 +0000https://faq.i3wm.org/question/2966/what-is-wrong-in-this-use-of-focus-parent/?comment=2985#comment-2985Comment by geo909 for Your usage of <code>focus parent</code> is correct.
