Sorry for the stupid question but I am new with Linux (I am using Gnome classic with Ubuntu 12.04) and I cannot set compiz in order to obtain the rotating cube.

I have already installed compizconfig-setting-manager and also the extra (and fusion) plugins but:

  • even if I disable the desktop wall and enable cube and rotating cube, nothing happens;
  • even if I change into general settings the number of vertical and horizontal virtual size nothing happens.

What I need is (possibly) a step by step answer.

Thank you

Ok...I solved my problem by using the command.

compiz --replace

which I have found looking around.

Can someone explain me what I have precisely performed with this command?

Thanks in advance

What guidelines or instructions you followed? Edit the question to include that. – Anwar Shah Jul 4 '12 at 9:36
link and other italian pages. I think also that one issue could be the fact that until few days ago I used unity and my Gnome classic "derive" from the fact that I am using Gnome Shell...could it be? – Keynesian Jul 4 '12 at 9:42
You can check this link for a good introduction. also do a compiz profile reset with compizconfig-settings-manager – Anwar Shah Jul 4 '12 at 9:52
I've done what you have suggested and after the reset I have changed to 4 the horizontal virtual size and I have crossed Desktop Cube and Rotate Cube. Anyway, it doesn't work yet. – Keynesian Jul 4 '12 at 10:01
check this question then update the question if you have any other query – Anwar Shah Jul 4 '12 at 10:07

With compiz --replace, you have replaced any existing window manager with Compiz; if you were already using Compiz, you have "reset" (or re-initialized) it -- which probably explains why this command solved your problem by finally applying your custom settings.

A new problem had emerged. Now I cannot move any window from one desktop to another; moreover I cannot resize the windows. Can you tell me what to do? – Keynesian Jul 4 '12 at 11:41
@Keynesian: first, try rebooting. Otherwise, could you please start a new question, describing the steps you took to change Compiz from its default configuration? After that the solution should be easy (because I or others can attempt to replicate your problem if necessary). – izx Jul 4 '12 at 12:14
