Terminator is very powerful at organizing several computers or servers due to the split window and group all function. But here's the deal: I created my own Layout and would appreciate it to load at startup of terminator. Is that possible?
After saving your layout (as per mhnagaoka's answer), you can make your changes used by default by editing the config file.
I use the same way like mhnagaoka suggested, but I made usable from the launcher in Unity. Had also an issue with plain "terminator -l my_default" command, so somewhere I found a proposal to use additional flags
The final Command is following terminator -m -b -l my_default.
Now you need to modify terminator.desktop entry for Unity.
Go to your application folder, in my case it was /usr/share/applications. You need to have root permissions to edit with your text editor terminator.desktop.
In my case it was, sudo vim terminator.desktop.
replace the Exec argument to your Command.
Now you can add the entry to your Unity Launcher, and it should always open your custom layout on the start.
