On the google hangounts support board it says:

Issues screen sharing on Linux devices.

If you are having trouble screen sharing on Linux, please check that window compositing is enabled.

I am having issues screensharing on my ubuntu 12.04. How can I turn this on?

If Compiz doesn't work well on your computer, you can always try to enable Metacity's compositing manager. To do this, press Ctrl+Alt+T (opens a terminal window), then run gconf-editor. On the left side, browse to apps > metacity > general, then check the box corresponding to compositing_manager on the right.

[EDIT]: Visual help to configuration manager:

  1. Open dash and type Config on the search field. Proceed to selecting configuration editor.Open conf editor

  2. After you have opened the configuration editor, browse to apps > metacity > general, then check the box corresponding to compositing_manager on the right, like this (my mouse pointer shows the box you should check): Compositing manager

Hope this helped.

Thanks - I went to Appearance (via System Settings, I don't have System Preferences) but it looks like this: No "Visual Effects" tab at all? gconf-editor is not found btw. I assume I need to sudo apt get something for it? – George Mauer Aug 22 '12 at 14:02
No, I do not think you need to download something, just open Dash, and type in the search field Configuration and from the results select configuration editor. I will post some screenshots in my answer case you won't find it. – NlightNFotis Aug 22 '12 at 14:05
Zilch. Only thing that returns searching for "configuration" is some code files from some projects I've been on. – George Mauer Aug 22 '12 at 14:10
Just in case, why don't you open a terminal, and type sudo apt-get install gconf-editor? – NlightNFotis Aug 22 '12 at 14:12
Thanks, I had to apt-get install it – George Mauer Aug 22 '12 at 15:07
