Have you been annoyed by not being able to move your dialogs in Mint 13 Cinnamon? This simple tutorial will show you how to disable the “attach_modal_dialogs” setting. I really do not like these new dialogs and found a solution for Gnome Shell 3. From there it was not hard to work out how to change the setting in Cinnamon.
Gnome Configuration Editor
If you do not have the Gnome Configuration Editor, you can install it with the following command or use your package manager.
sudo apt-get install gconf-editor
Run the Gnome Configuration Editor with the following command in the terminal or by pressing Alt+F2.
Untick the option “attach_modal_dialogs” at
/ -> cinnamon -> windows -> attach_modal_dialogs
Restart The Desktop
Press Alt+F2 and type r in the text box then press enter. You now have dialogs that are not attached to parent windows that you can move.
