I am running 12.04 64-bit, and I have had a bit of trouble with Ubuntu. First, I installed 12.10 32-bit, and then I tried to install 64-bit, but it didn't work. Then, one of my friends, who has the exact same computer as I do, said that he installed 12.04 LTS 64-bit, and it ran perfectly. So I tried doing that, and then upgrading to 12.10 from the terminal, however that didn't work either. Then I decided to run 12.04, because it was 64-bit, but once I installed it, I had to update a couple of things (85 to be exact) and I also updated a driver. I rebooted my computer, because you have to do that after you update something, and then the mousepad stopped working. I can click the buttons, but I can't move it. When I was running Windows 7, and when I was running 12.10 32-bit, it worked fine, and I don't know what to do. It has to be said, that I am a complete Ubuntu Novice, and I don't really know what to do.
Here are my specs: - Packard Bell Easynote LM series - 640 GB HDD - 6 GB DDR3 Ram - AMD Phenom II X2 N660
