Ubuntu 12.04 desktop loads pretty slow after password entry

Well, I have an Ubuntu 12.04 running on a Core i7 laptop, with an SSD
disk. The laptop is a dual-boot. I experience a very large delay between
the password entry and the Desktop showing up. In general, the process
looks like this:
Grub loads fast.
I choose Ubuntu from the list.
Password prompt loads fast.
I enter the password for my user. The computer kinda hangs. The Wifi is
flashing, but the hard drive light is not flashing a lot. This takes about
30-40 seconds.
The Desktop loads in a flash
I've experienced this issue in the past, with my standard HDD. Then I
removed UbuntuOne as advised in a thread that I've seen. This seems to
have helped for a while. Then I migrated to the SSD. The computer loaded
pretty fast for a while, then this started happening. I don't think that
it is related to the SSD, though.
