Maximus GNOME Shell Extension

The Maximus GNOME Shell Extension attempts to emulate the Maximus package for the Ubuntu Netbook Remix.

That is, it removes decoration (i.e. the title bar) from maximised windows, saving vertical real estate. For example, Google Chrome does this by default. Useful for netbooks with small screens.

With Maximus Without Maximus
Using Maximus Without Maximus (title bar shows)

NOTE: with the titlebar of a window hidden, you may find it difficult to unmaximise/move a window. In this case, I recommend either remembering your system's keyboard shortcut for un/maximising a window (e.g. Alt+F10 on Fedora), or use the Window Options GNOME shell extension which adds a drop-down menu to the title bar in the top panel with these options (shameless plug, I wrote that one).

By default, only fully-maximised windows are undecorated. If you also want to undecorate half-maximised windows, edit the line in extension.js to change this line:

const undecorateHalfMaximised = false;

to this (change the false to true):

const undecorateHalfMaximised = true;


One-click install from!

From this website:

  1. Download the .zip file on the Downloads page.
  2. Open gnome-tweak-tool, go to "Shell Extensions", "Install Extension" and select the .zip file.

Alternatively (developers?):

  1. Checkout the repository: hg clone
  2. Update to the stable branch (the default branch is NOT guaranteed to work!).
  3. Copy the folder to .local/share/gnome-shell/extensions.
  4. If on GNOME 3.2, use dconf-editor and modify the key /org/gnome/shell/enabled-extensions to include ''. If on GNOME 3.4, then just do gnome-shell-extension-tool -e

All together now:

hg clone
cd maximus-gnome-shell-extension
hg up stable
cp -r ~/.local/share/gnome-shell/extensions
# if you have GNOME 3.4:
gnome-shell-extension-tool -e
# if you have GNOME 3.2:
dconf read '/org/gnome/shell/enabled-extensions' | sed -r -e 's#\[(.+)\]#dconf write "/org/gnome/shell/enabled-extensions" "[\1, '\'\'']"#' | /bin/sh

Branch Info (for developers)

  • 'Stable' branch works with GNOME 3.2 and GNOME 3.4. No fancy gsettings or UI for setting options (this extension doesn't have options for the moment).
  • 'Default' branch - where development happens. It is not guaranteed to be stable at any commit.
