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!)

graphical glitch still in place

Have you tried updating device drivers?

Go into the dash menu and open Additional Drivers and select the latest proprietary driver on the list. It should say something like NVIDIA Binary Driver. Afterwards, press Apply Changes and then reboot.

It should look something like this:

additional drivers dialog

If you have an Optimus laptop, you might need to install Bumblebee.

If you can't use the settings menu because of your display issues, you can install proprietary drivers if you manage to get into a shell by typing:

sudo apt-get update
sudo apt-get install nvidia-352

This will install Nvidia's 352.63 driver which is the latest stable one at the time of posting as far as I know (future readers may need to adjust the command. See How do I install the Nvidia drivers?). More information can be found here on the Ubuntu Help Wiki.
