Comment 46 for bug 491521

I once followed the tutorial at http://janhouse.deviantart.com/art/Gnome-quot-Aero-look-quot-tutorial-142265951?offset=10#comments to get rgba gtk on Karmic. I added the desktop team ppa in lucid and tried to see what from the tutorial still applied to lucid with the ppa. (I made a how to at https://launchpad.net/~ubuntu-desktop/+archive/ppa/+packages). With the rgba, the screensaver is fully tranparent wherever there should be black. I have attached a screenshot.
