Yesterday I upgraded Ubuntu from 11.04 to 11.10.
There is a nice effect of alt tab switcher with windows preview in 11.10 but with my system only simple alt tab switcher is working without effects.
I have Nvidia 1GB graphics card. I was using ubuntu classic with 11.04 as driver was not working with it but with 11.10 now nvidia driver is working and I want all unity effects.
I have installed compiz setting manager but can't able to enable alt tab switcher effects from anywhere.
