A window border theme for Cinnamon and Gnome Desktops that gets rid of almost all window decorations.

This project is obsolete

Since Linux Mint 21, this approach to hiding title bars does not work anymore. Instead, you can use the extension Cinnamon Maximus. (Note that, after installing the extension, you need to enable it using the plus button in the list of installed extensions)

No Titlebars theme for Cinnamon and the Gnome Desktop Environment

This is a window border theme for Cinnamon that disables almost all window decorations. It's intended for people who use keybindings to do everything that the titlebar normally does, and who would like to regain the screen space lost on window decorations.

Note that this theme removes all titlebars. If you haven't set any keybindings before turning this theme on, you may find it pretty difficult to use your desktop environment. You will need at least a keybinding for closing windows, one for (un)maximizing windows and one for moving windows around.

This should also work with Gnome desktops, but I have only tried it with Cinnamon so I can't say for sure. Let me know if it doesn't.

Installation

Download this repository as a ZIP, unpack it and move the “No titlebars” folder into ~/.themes/. If you don't have a .themes folder in your home directory, you should create it yourself. You can delete README.md and the screenshot, they're only there for the Github page.

Open up the theme settings for your desktop environment and choose “No titlebars” for window borders. It should start working immediately after that.
