As in title - is it possible to use Compiz with GNOME Flashback on Ubuntu 20.04 ? If yes, how ? It would be nice to have some features like window overview screen with miniatures of all open windows, something that Compiz provided in the older version of Ubuntu.

The corresponding compiz-gnome package is in place.

So it should work after you install it with

sudo apt-get install compiz-gnome

and optionally set settings using CompizConfig Settings Manager (ccsm):

sudo apt-get install compizconfig-settings-manager

Then select relevant session on login screen.


Yes, Gnome Session Flashback can be used both with metacity and with compiz. In addition to installing gnome-session-flashback, you need to install compiz::

sudo apt-get -y install compiz-plugins compizconfig-settings-manager

Select the "GNOME Flashback (Compiz)" session during login.

  • Compiz was not installed by default with system installation. I needed also to install compiz itself, not only compiz-plugins and compizconfig-settings-manager. After installing all these and restarting the computer, I was able to choose GNOME Flashback Compiz session.

    Installing compiz-plugins will automatically pull in compiz as well.

  • After those package installs, I could get compiz settings to run alright, but couldn't get any of its effects (e.g. the window switching cube) actually happen after being selected. Maybe I really need the flashback version of gnome, but wasn't brave enough to make the switch from the version of gnome shipped with 20.04. Didn't get a new session login option either. Some extra steps listed here feel outdated.
