I am using Toshiba satellite c55I laptop and i have just upgraded to the newest version of Ubuntu 14.04 LTS 64 bit. I did this for the added security benefits of Ubuntu 14.04.2 LTS, and I have experienced an odd black-fuzz after entering my password when logging in. It seams to crash but then moments later boot smoothly up to my desktop.
I had some issue with my login screen on 14.04.1 where my desktop background didn't load. As well as being slow to boot to my desktop. Now its the same issue but with a bit of black-fuzz within the screen.This doesn't happen after the first boot up only when the computer is booted for the first time. After that its business as usual.This does not seem to effect the computer in any way, shape, or form. if i might add the laptop runs great with the OS.
