If you left it for a while, did it eventually complete the login? The fact that Bluedevil was started indicates that the application startup phase had been completed - so it may simply have been that the splash was not being killed, or that Plasma Desktop was hanging during startup.

I guess I can still reproduce the problem, I'm just not sure for which processes I should be looking for. Is there a documentation of KDE startup sequence?

bcooksley Administrator Posts 19765 Karma 87 OS	Re: KDE 4.10.2 freezes at startup Fri May 03, 2013 10:00 am It looks like zombie processes are not getting cleaned up properly for unknown reasons. Were there any other KDE related processes of note, such as those which may be hung in a "D" (or blocked) state. I'm not sure why this is occurring unfortunately.
