Downgrade from 3.12 Staging.

[Christian Dysthe]

Hi,

The last time I tried to downgrade from staging I was left unable to
login. When I look closer important packages like gdm was removed when
using ppa-purge. Is this a known problem, or did something go wrong for
me? I would like to know before I try again. If there is a problem, is
there a workaround for downgrading?
