Try to see if this answer help you: --- if it does, comment/modify the question, please. Anyway, you need to give much more info about your hardware; at least the graphic card you have and the drivers you are using. – Rmano Apr 1 '14 at 14:44
Hi, thanks for the pointer. I just gave that a go to no luck. I am using an intel nuc with celeron processor. – albany Apr 1 '14 at 14:59
Is there anything else I can try? – albany Apr 1 '14 at 15:00
I really don't know --- you can try the other answers to the question I pointed before. BTW, please add the data of your computer to the question (better hint at it in the title, too --- try to be more search-friendly and see if you can attract some help more useful than mine...) – Rmano Apr 1 '14 at 15:08
this answer solves the question completely. Tested and worked on all ubuntu versions – Yash Bhalgat Dec 11 '14 at 20:44

Press Ctrl+F1 to go to shell login "tty1" and enter your username and password Then type
sudo service lightdm restart
and then enter your password again. It'll do the trick.
