I have had the same experience because of my hardware. It seems Ubuntu from 13 has much 3d grahics that don't work well with onboard GPU. Since my pc was a business pc and lacked fancy high performance hardware I was advices by ubuntu to use lubuntu and I must confess lubuntu is super light fast on my system. It's very much the same as ubuntu but only better. Doing that saved me lots of time in trying to solve my hardware issues that I don't have time for since time is money. You can just install lxde in your current ubuntu and it will have a lubuntu choice at the log in screen. You'll need something like 1GB free space for that to install. As for me I cleaned installed lubuntu since I didn't have much complicated files that need advanced backup bacuse I just had documents. Good luck with wonderful and free ubuntu. Saves me alot of cash.
