"Fade to Desktop" and "Show desktop" plug-ins should be automagically disabled and hidden in CCSM if the Ubuntu Unity Plugin is enabled

I think it's poor design to give Compiz any knowledge of Unity. It should only work the other way.

I think it is poor design to present "fake" options to the user. Once Unity is activated those plug-ins are completely useless, do not work and only can frustrate users trying to do anything with them.

What is the problem of having Compiz know about Unity ?

But after all just CCSM has to know about the state of the unityshell plug-in and in this case automatically hide and disable those 2 non-working plug-ins.
This more intelligent behavior would also fix:

bug 1006429 and bug 1006434

I have to mark this bug as "new", otherwise I cannot find it anymore via the "reported bugs" launchpad function which seems to automatically filter invalid and opinion bugs.

Or we could probably use/add <feature>showdesktop</feature> to unity/plugins/unityshell.xml.in to display a warning like it is already used for various other plug-ins which are not allowed to provide the same feature twice.

The dialogue would look like this:

"Plugin Unity provides feature showdesktop which is also provided by Show Desktop/Fade to Desktop".
 Don't enable Show/Fade Desktop Disable Unity

Should I implement that ?

Example screenshot (here the feature is not showdesktop, but edgeresistance and the user tries to enable Snapping Windows while having the same feature already provided by Wobbly Windows).

Actually this fix has to be made in unity/plugins/unityshell.xml.in, so I am adding Unity to this report.

Both plugins work perfectly for me. In the case of Show Desktop it's just a question of setting it to start after Unity, using Gconf Editor.

@megatron: That are actually good news. :) With default settings they do not work.

I will verify your observation, and if working, change the startup sequence accordingly and remove the patch that prevents them from starting together (unityshell+showdesktop/unityshell+fadetodesktop).

The showdesktop plug-in is far superior in visual appearance compared to the fade effect Unity uses, so the showdesktop plug-in revealing the desktop by moving them to the edges should of course not be deactivated if there is a way to make this plug-in work together with Unity without creation of new problems.

@megatron:
I can confirm your observations and have filed a new bug and will provide a fix soon. :)
The problem will be tracked here: bug 1067534.
