I've already seen this question:
How to list all the packages which are installed from PPAs?
It only works for packages installed from PPAs where the PPA repository is still added to the system.
Is there a way to get the same kind of list but including all packages from all PPA repositories that are current added or have been added in the past?
Expand the "Installed Software" item in Ubuntu Software Center. You'll see a list of all the different repositories that you've enabled. Clicking on the repo will show you the packages you've installed from each.
It's actually not as hard as I thought it might be - and it's probably quite a valuable filter to have!
First you select which status you want to show. I selected "Installed" amongst a couple of others but that's probably all you need.
The real nuts and bolts come from the properties screen. In there you can set the origin requirements. All I did was exclude anything from archive.ubuntu.com (which is the mirror I use). If you're using another mirror, change that string.
The alternative would be to disable all the PPAs in sources and then look at the local section.

You may search for installed obsolete packages, either locally installed or their source repository is disabled)
Also if you want both obsolete + ppa ones:
