Fast, lightweight alternative to Compiz' Expo Plugin?
Solution 1:
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.
