In an earlier version of Ubuntu with Compiz I'm pretty sure there was a useful setting to enable seeing what's behind the current window by clicking and holding the title bar, which then changed the current window's opacity to something like 10 percent.

Is there any way to achieve this in Ubuntu 11.10?

  • Was it the Opacity plug in?, because that it's still in Compiz in 11.10. Nov 30, 2011 at 9:05
  • I looked at both the Opacify and the Opacity, Brightness, etc. plugins in Compiz but could not see a way to achieve the desired result

Have you tried https://launchpad.net/~unity-team/+archive/compiz-testing

add this to your sources.list

deb http://ppa.launchpad.net/unity-team/compiz-testing/ubuntu oneiric main deb-src http://ppa.launchpad.net/unity-team/compiz-testing/ubuntu oneiric main


You can update your system with unsupported packages from this untrusted PPA by adding ppa:unity-team/compiz-testing to your system's Software Sources

sudo apt-get install compiz-plugins-main

you will also want to add this

sudo apt-get install compizconfig-settings-manager
