Often, I find issues with the internals of Ubuntu and I don't know how to effectively assign the bug to the right project/audience.
Take this bug for example, regarding multiple monitor support. I'd like to file this bug against Gnome, but I don't know which of the many Gnome projects apply here (or is it actually a problem with X? or gtk?). I can't even search for gnome-related projects or packages, as Launchpad complains:
Too many matches. Please try to narrow your search.
I've tried asking on #ubuntu and #ubuntu+1 but received no help due to the very high amount of ongoing activity: IRC just doesn't scale.
As a result I had to mark the bug generically against Ubuntu and now it's just one of a dozen emails that the poor souls subscribed to the project receive on a hourly basis. I doubt the bug will get any attention this way.
How can I effectively target a bug with non-frontend components of Ubuntu? Where can I get help with targeting such bugs?
