I'm running Ubuntu 14.04 on the new Dell XPS13.
I never needed a login, I was just able to boot and my desktop would show up.
It doesn't anymore; I can still switch to TTY to get work done.

What did I do? I uninstalled/purged/autoremoved Google Chrome, the laptop then froze. After I cut the power and restarted it was like this.

I did not install Nvidia drivers (I did after it was broken to try and fix my laptop).
I have uninstalled Ubuntu desktop using Tasksel, but I do still have a graphical Ubuntu start for a couple of seconds. Very weird.

I've uninstalled nearly everything using tasksel (except the `printserver` and `tomcat` - which I can't uninstall `aptitude failed 100`.

Any help would be greatly appreciated.

EDIT: i did `apt-get update` to try and fix the `aptitude` problem, which didn't help.
