I'm no expert on gdm startup, but after reviewing the journal entries, nothing immediately jumps out. The only gaps in startup are likely just due to other parts of gnome or the system starting at that time. For what it is worth, the following were the only two delays in startup that caught my eye.

(this last entry doesn't make a lot of sense to me, you have VT originally on 1, it changes to 2, the login window is on 1 and then the login window is killed - like you have auto-login or something, an finally the "active VT is not initial VT, so ignoring" is odd looking, but may be 100% normal -- it's gnome after all...) Others will have to chime in with more specifics if they see anything, but from the journal snippets posted, your problem seems to be elsewhere. -- David C. Rankin, J.D.,P.E.
