I've been using ubuntu since version 10.04 and so far I was never in a situation I could not solve on my own googling other people's questions. In this case, there seem to be such a variety of reasons for ubuntu starting slow that it's hard for me to find the solution.
I have Ubuntu 12.04 installed on a Samsung RC530 laptop
The problem is the following: it takes several minutes for ubuntu to start(first until the login appears and then until it loads, being the first one the slowest)
I've checked a couple of questions including http://ubuntuforums.org/archive/index.php/t-2137435.html but I'm still not sure if I have the same problem(that's what I'm trying to figure out!)
in order to speed up the answers here goes the output of dmesg:
