I come here posing a question. I had installed Ubuntu 12.04 lts some time ago, and had this same problem. Somehow i got around it but haven't been able to replicate it. Now I am unable to install Ubuntu 13.10 - 11.10 on my Dell Vostro 3555 even with "nomodeset" "apci=off" and others. The attached picture shows what it results in if I use "nomodeset". This isn't the only thing that has happened. If I don't set other options, It just hangs on the Ubuntu splash screen. If anyone has any way to help me install Ubuntu, that would be appreciated.
