I had been using Ubuntu 13.04 and I chose the upgrade option from the Ubuntu live CD and chose to keep the installed file as it is. The installation successfully completed with an error message saying
some older packages may have to be reinstalled. I restarted the computer, but now I can't login to the computer in GUI mode. It gives an error message that it can't find graphics drivers. When I click on the only available button OK, I get the following dialogue box:
and then when I click the first option I get this one :

Clicking the second option gives the following:
and clicking OK gives the same dialogue box recursively.
Third option shows a error log file and fourth option lets me smoothly use the Ubuntu 14.04 in GUI mode and my files are safe in my drive.
So how do I get rid of this problem? I assume graphics drivers come with Ubuntu 14.04 itself.
