I was dumb and removed all the window effects under the compiz manager animation settings and I was wondering how to reset the window effects to what they were by default (using gnome).
Update 1
I think there's been some confusion regarding what, exactly, is being asked. I'm not asking how to switch effect levels. I'm asking how to bring back the default list of visual effects that are enabled once you choose "custom" in the effects preferences window. I removd all of the effects under the "open window" tab in "animations" and I'd like to know how to get them back.
