I upgraded to Intrepid Ibex Alpha 2 (the second alpha release of Ubuntu 8.10) with the instructions here:
I had reported my "no sound" bug on Launchpad they suggested I upgrade to Alpha 2. I did that, but now I can't log on normally or after I enter my screen name and password the screen goes white and stays that way. My mouse moves across it but it just doesn't work in any other way. I have to log in using a Gnome default session. When I upgraded, it asked me to remove approx. 30 packages that were "obsolete" and now when I try to do some things, like watch videos it tells me that I can't but doesn't tell me why. My custom theme doesn't work anymore either.
Is there a way to undo the upgrade or am I s.o.l.?
