I recently tried to install Ubuntu 14 Lts alongside Windows XP pro on my 2005 dell dimension E510. Everything appeared to be working correctly until I tried to log in, at which point it froze with a blank color background, which would flicker to black every other time I hit a key or clicked the mouse. I then tried booting in graphical safe mode at which point it told me that it could not configure the graphics settings. Does any body know what's going on. Thank you for any suggestions.
