I installed Terminator using following commands.
sudo add-apt-repository ppa:gnome-terminator
sudo apt-get update
sudo apt-get install terminator
It seems like it's not loading .bashrc file. When I open Vim in terminator, it's not even loading .vimrc file.
I can't even change Preferences->Profile->Colors.
But everything is working fine in gnome-terminal.
Right click on the terminator window and select preferences.
On profiles tab, tick check Run command as login shell.
This will enable terminator to read the rc files on startup.
