I downloaded Ubuntu onto my HP computer tonight and I am unable to login. When I restart my computer, it shows me a black screen and asks for my login name and password which I provide. It then says something like kelly@kellybrown and wants me to type something, but no matter what I type it doesn't let me go past the screen. What can I do or how do I get past this screen. Did I do something wrong during the download?

  • It would be interesting to see if you can get to your normal desktop environment by entering the command sudo service lightdm start which will bring up your normal graphical login screen and then you can log in to your desktop from there. After that you could use the built-in Additional Drivers utility to check if your computer is missing a proprietary graphics display driver. – karel Jun 17 '14 at 3:55
  • that does not work either. – user294229 Jun 17 '14 at 16:37
  • Please login with your username and password from the black screen and then provide the results of running the command: lspci -nn | grep VGA which will tell whether you are missing a display graphics driver, which can also be installed from the same screen. – karel Jun 17 '14 at 16:49
  • after I type that in it says 00:12.0 VGA compatible controller [0300]: NVIDIA Corporation C67 [GeForce 7150M / nForce 6 30MJ [10de:0531] (rev a2) – user294229 Jun 17 '14 at 16:56
  • Please login with your username and password from the black screen. Your Nvidia GeForce 7150M is an older GPU, so I recommend that instead of the current proprietary Nvidia graphics driver you instead the next older one. Enter this command: sudo apt-get install nvidia-173. Then to enable the graphics driver that you installed reboot by running this command: sudo shutdown -r now. Please comment about the results because you may still need to do one more step. – karel Jun 17 '14 at 17:09

This is happening because you don't have the GUI installed in your version of Ubuntu. To solve this, type the following commands after you login to Ubuntu and get this - kelly@kellybrown

sudo apt-get update
sudo apt-get install ubuntu-desktop
sudo reboot

You need a working internet connection for this.


You might have to reinstall Ubuntu.

By the way, have you downloaded the correct iso? You can download the desktop version of Ubuntu from this page on the official site.

  • what if I downloaded the wrong one? how do I change it to the correct one if I cannot get into my computer? – user294229 Jun 17 '14 at 16:24
  • Can you boot to your Ubuntu using the "Try Ubuntu" option? – Raphael Jun 17 '14 at 16:27

    As you have downloaded the server edition of Ubuntu, you can browse the web but it includes a lot of commands. Can't you download Ubuntu Desktop from somewhere else? – Raphael Jun 17 '14 at 17:31

    You can atleast download the desktop iso to your tab. – Raphael Jun 17 '14 at 17:41

    Yes, you can save it to a USB or rather burn it to a USB or DVD from another computer with a working OS. – Raphael Jun 18 '14 at 4:34
