I am very new to Ubuntu. I followed this YouTube tutorial on replacing Windows with Ubuntu on my crummy laptop. When the installer loaded up there were resolution problems where two versions of the screen were being displayed at once, with an overlap in the middle (almost like a venn diagram). I assumed this was a little glitch and that it would disappear after finishing the installation. As far as I can tell, it didn't. A couple of reboots later, it's still there.
I am running the 64-bit version of 14.04.3 LTS. The laptop has Nvidia graphics (could it be as simple as trying the 32-bit version? I have the specs for 64!)
