built a new computer yesterday and the specs are as follows:

AMD A6 5400k process with AMD Radeon HD7540D graphics (built-in)

FM2-A75IA-E53 mobo

8GB Crucial RAM

I can install and run Ubuntu 12.04. But if I try to update to Ubuntu 12.10 or just install 12.10, the computer just hangs on boot at a blank purple screen.

Note: I tried 13.04, same issue.

Please help, I would very much like to use a newer Ubuntu than 12.04!

Figured this out. For whatever reason it would not boot if the live USB was plugged into a USB3.0 port on the computer. After switching to one of the 2 USB 2 ports it worked correctly. Sounds like a bug with USB3.0 in Ubuntu. Worked properly on other machines though (Driver problem?).
