I've been seeing this problem on my desktop since after 16.04 was released. Thinking that bug 1559595 could be my problem I appended on 3/26/16. Since this is intermittent I can't say for certain that any release update since March has not failed on this desktop. Run the same 16.04 distribution on my laptop and never seen this problem.

Been having an intermittent problem booting (started on 16.04 and continues across multiple system rebuilds and 16.10) where just after entering my PW the screen goes blank for about 90 seconds. After that interval the normal desktop appears and all is well. Will supply a journal boot log of a failing boot (boot_0704.txt) and a normal boot log (boot_0704_good.txt). Do see in the failing log and all others that I have looked at a gnome-session timeout (time 06:16:41). Don't see this type of entry in the good log but haven't examined many non- failure logs.
