These effects worked fine for me on F8, and I was disappointed when they stopped working in F10. Instead, the default fade effect configured by F10 seemed to override anything I specified in the Settings Manager. So I struggled with it for a few hours and then gave up for a few months.
Not more than 10 minutes ago I decided to see if anyone had been able to fix it and came across your post, where you mention the backend. I have been using the flat file backend, so I decided to try switching to GConf (yes, I know it makes no logical sense, based on the fact that you say you have used both), and lo and behold, suddenly my Magic Lamp minimize effect is working. (The effect changed to a Zoom (I think) and then I toggled the Animations and Animations Add-On plugins and the effect became the Magic Lamp that I had configured.)
So, as you would expect, Compiz is getting its settings from somewhere
- either the flat file or GConf. For me, there must be something conflicting in the flat file; some hang over from an earlier version of Compiz that is confusing the minimize effect. I think that switching to the GConf backend, which I had never used before, caused Compiz to create a consistent set of settings in the GConf backend, based on those that it understood from the flat file backend. It then used the consistent set, and ceased being confused.
My advice to you, to fix your problem, would be:
- Configure things the way you like using the flat file backend.
- Install and run gconf-editor, and clean out the Compiz settings from wherever they occur.
- Switch over to using the GConf backend.
- Finally, go back and make sure the settings match what you originally desired, possibly toggling the Animation plugin to make sure it is reset.
EDIT: On further investigation, it seems that all of my customisations were lost when I switched the back end, and I am now going through and redoing all of them. Let's pretend like my comment above reflects that reality.
