Want to remove the titlebar of the terminal. It would helpful if there is a way to generically do it for all the windows ? If not possible, still if it would be helpful if I can remove or hide the titlebar for the terminal itself.
I don't know which terminal you use, but on xfce4-terminal, you go to menu Edit -> Preferences, select View tab and under Opening new windows section, there is an option to disable system title bar for future terminal (not for the one already open but for all new ones). Next to it there are options to disable menu bar and toolbar as well as the size for new windows.
