Open Windows Centered (14.04/16.04/18.04)


Ubuntu 18.04:

Open a terminal and run this command:

gsettings set org.gnome.mutter center-new-windows 'true'

To change it back to the default behavior, run this command:

gsettings set org.gnome.mutter center-new-windows 'false'

Ubuntu 14.04 / 16.04:

Either search for CompizConfig in the Ubuntu Software Center, or type this command:

sudo apt install compizconfig-settings-manager

Once CompizConfig Settings Manager is installed, run it and go to Window Management > Place Windows and set "Placement Mode" to Centered.

Please note that this requires functioning 3D, Compiz, and Unity 3D (not 2D).
