terminator vs ubuntu 18.10 - broadcast issue

terminator is a very good graphical terminal emulator for linux. Its main advantage is that it allows to split the screen into several terminal windows and add tabs with additional split screens. On top of that, on can broadcast from one terminal to others.

There is an issue with broadcasting in ubuntu 18.10 with its standard desktop environment. every key that is pressed in the sending terminal is written twice in the receiving ones.

as pointed out in a comment on a but report related to this issue, one can unset the GTK_IM_MODULE environment variable prior to starting terminator which will work around the problem.

the easiest way to do this is to add a bash alias overwriting the terminator command. If you only need to do this for one user, you can put it in the users ~/.bash_aliases file. otherwise one could add a file to /etc/profile.d/ to do this for all users.

alias terminator='GTK_IM_MODULE= setsid terminator'

you will need to log out of your current gnome session and log back in for this to take effect.
