I'm not pretty sure what is the problem. But I already installed the Compiz Manager Settings (I want to be able to do zoom for creating tutorials) on my Ubuntu 18.04 (Bionic Beaver) but no matter if I check the box for enabling the effect and configure the hotkeys no one effect is working.

EDIT 1. I follow the answer of KYAA7 but I don't know how to use Dconf in order to Compiz to work. I installed dConf editor as in the link provided by him. But it looks a bit different from the shown there. Here a screenshot:

As you can see there is no Compiz folder or something like that, also is not in the folder apps. What I suppose to do with this software for using Compiz and their zoom feature?

    I am not sure, but do not think the default gnome desktop uses Compiz settings, might have to install unity if you want compiz. – crip659 Mar 23 '20 at 16:25
  • and... is this recommended? I mean is there any conflict having unity and gnome? – José Marín Mar 23 '20 at 17:00

    Find unity works very well with gnome, but to just have compiz might not be worth it. K7AAY has an answer below if you like gnome better than unity. – crip659 Mar 23 '20 at 19:15
  • Well, I maybe will try the answer of K7AAY. I also think that installing so many things just for use a zoom feature is not worth it. – José Marín Mar 23 '20 at 20:44

    Understand, maybe google gnome desktop zoom. Might find something easy to do instead of installing stuff. Gnome should have something like that. – crip659 Mar 23 '20 at 21:22
  • Yes, There is the option of Zoom in Accesibility. But it's not the kind of thing I need for a tutotial. Thank you any way. I'm going to end this search by a while. – José Marín Mar 23 '20 at 21:30

Compiz needs the GNOME3 Shell extension put-windows. Then, you can install Compiz with sudo apt update && sudo apt install gnome-session-flashback. Compiz settings are adjusted with dconf which is explained here.

  • I did what you said til the dconf part. How can I use dconf for using Compiz? I'm an average user, just wan to use the Zoom of Compiz. – José Marín Mar 23 '20 at 21:04
  • The thing is I'm still unable to make Compiz (through the CompizConfig Settings Manager) works and I don't understand dconf. – José Marín Mar 23 '20 at 21:14

To answer the OP's edit: if you have got to the point where compiz works, you will find the keys you want under /org/compiz in dconf-editor. You can also look specifically for the zoom keys with the search function.

If you want a compiz-specific program for editing those keys, try ccsm: install it with sudo apt-get install compizconfig-settings-manager.
