I've installed Ubuntu 12.04 on clean PC from Live mode. After reboot I can only see purple screen - no boot splash etc, can't access to alternative screens like ctrl+alt-f6 etc, but I can hear login prompt sound. I can access recovery mode, so I guess it's kinda video drivers problem. But I'd like to know any alternative suggestions. Thanks.

Installed nvidia drivers from recovery mode and it's working! – Noiwex Apr 30 '12 at 14:22
It happened to me. What I did was to install all over again. I am not really sure about the root of the problem. What kind of computer are you using? Did you tried attaching another monitor (if it is a laptop). At first, Ubuntu did not recognized my video card, so that might be the problem. – Miguel Callejas Apr 30 '12 at 14:24

The problem seems to be with the Video Drivers.

  1. Enter recovery mode.
  2. Log in with your user name and password.
  3. Install the video drivers for your computer.

If you don't know how to install your video dirvers, follow this guide.
