I managed to install Gnome classic Metacity on Ubuntu 14.10 using this:
sudo apt-get install gnome-session-fallback
I can user the Super (Windows) key to maximize and restore the windows with the Up and Down arrows.
I would also like to have the Aero Snap effect with Super+left and Super+right, ideally also having it working with my external screen plugged.
I want this to work with Metacity, I would rather have it done in a quick and dirty way than having to move to something different than Metacity.
Any ideas?
