Try pressing ctl-alt-f8 during the boot. This should open a text screen 
which will show reports from each of the services as it starts up, and 
you can see whether one or two of them are taking a long time to start.

FYI, people are working on making the linux boot process faster - I 
think one of the projects is called initng(?) The idea is rather than 
starting the processes and services in series at the moment, to have an 
init system that knows which services depend on others so that they can 
be started partially in parallel. This would make booting much faster, 
but hasn't been brought into ubuntu yet.
