This question already has an answer here:
This is my first time with Ubuntu (or any Linux distro for that matter). I installed Ubuntu 14.04 alongside windows 7. The initial install went flawlessly without any errors. After the install, I was able to login with the user I created, and then it booted up to a blank purplish screen. The only thing showing is my cursor. Left or right clicking doesn't bring up any options. I left it for an hour thinking it is still installing. Still has the blank screen. I reloaded the DVD thinking I will get a 'repair' option, but only get 'Try Ubuntu' and 'install Ubuntu'. This is on a dell laptop. Can anyone please give me a detailed step by step fix? My first experience with Ubuntu isn't going too well.
