I was using ubuntu 2d till now along with compiz. now i installed gnome-shell and after that compiz effects are not working. Is there any way to get compiz effects to work,else is there any other similar packages?
Compiz and gnome-shell do not go hand-in-hands together... Third heading in the link provides more insight about it: https://live.gnome.org/GNOME3Myths
Also the mailing list post about compiz and gnome-shell might be of interest for you:
So as far as I know, you can't get effects equivalent to those provided by compiz in gnome-shell... You might try to look for the gnome-shell extensions with similar functionality.
In terminal: sudo apt-get install compizconfig-settings-manager and then run the program (ccsm) to edit compiz settings.
Have you attempted to type in
compiz --replace within the terminal? I had to do that for the Cinnamon shell, but I am not certain whether gnome uses metacity or compiz by default.
Or press ALT F2 to open up a command field and then type in
