Comment 21 for bug 579313

Indeed, in all recent Oneiric daily-lives, this occurs when "Try Ubuntu without installing" is selected from the text-based boot menu, but not when that menu is bypassed and "Try Ubuntu" is selected in the graphical ubiquity-dm dialog. Furthermore, after a complete installation is carried out with Ubiquity, the graphical live session stops exhibiting this behavior. There might be additional intricacies that I have not identified. Please see duplicate bug 798509 for details. I have tested this on two machines of different hardware, and Eric Appleman has posted here confirming for Oneiric as well. So far no one has reported following the above instructions on Oneiric and failing to reproduce this bug--it would probably be good of more people could test, to ensure this is really happening for everyone in Oneiric (as it appeared that it wasn't, in Lucid).

I am not sure if this is really a bug in plymouth, at least as it occurs in Oneiric. But I don't consider myself qualified to tell. In duplicate bug 798509, I posted some logs that I believe indicate this may be a problem with key mapping in X.

I've changed this bug's title and tagged it to make clear that this affects Oneiric. If no one objects soon, I'll edit the description to reflect that as well.
