Degraded performance in boot after installing the Gnome Desktop

Question

I installed Ubuntu 14.04 via a minimal CD. it looked like a terminal window so I did: apt-get install gnome and it downloaded a lot of stuff. Then I rebooted and created an account.

It's been taking Ubuntu a lot time to boot, I get a purple screen with four dots and they light up and unlight and then it says trying to make network connections. then wait up to 60 seconds for network connections and then finally it loads but it takes what it seems like 10 minutes.

I don't know much about Ubuntu or Linux and I don't know what to do. Below is my dmesg.txt

The first thing I see in the output you posted is this:
IPv6: wlan0: IPv6 duplicate address fe80::5a94:6bff:fe22:3680 detected!
which theoretically shouldn't happen, since ipv6 addresses use theoretically unique mac addresses as part of the address structure. So, somehow, you've been the subject of a statistical anomaly whether it be crafted or accidental.

Either way, network interfaces stalling will cause boot to stall until a much longer than normal timeout passes and boot resumes.
