Ubuntu – Is there an alternative to compiz

Compiz already has this in the form of the bicubic filter plugin.

As mentioned before, unity is stuck with compiz.

But if you are willing to experiment, I suggest the Gala WM of elementary

sudo add-apt-repository ppa:elementary-os/daily
sudo apt-get update
sudo apt-get install gala
gala --repĺace

I am unaware if this plays ok with Unity, I removed Unity on my mschine. I personally pair this with MATE Desktop.

For expo you would also need dconf-editor to tweak when its Expo is used. It does have default keypress but you can also assign a hot spot to activate Expo.
