title: Ubuntu 18.04 freezes after login
body: <p>Yesterday I installed Ubunted on my laptop (Dell XPS 15 9560) and the installation went fine. I plugged in the USB and created an ext4 partition, made a user with a password and everything.</p>
  
  <p>Then I boot up Ubuntu, it takes me to the log in screen, I type my password, and then all the UI except the mouse (which is frozen) disappears and nothing happens. </p>
  
  <p>I have tried reinstalling the desktop with <code>sudo apt-get install --reinstall ubuntu-desktop</code> and udating the Intel graphics driver, both of which didn't help</p>
  
  <p>(this is my first time asking a question here, so please go easy on me)</p>
