There are 2 Linux drivers, the privative and the open driver, you have the open driver installed try to install the privative driver. It's better if before uninstalling the video driver before install the new driver,

Try to reinstall the Xorg driver on a terminal (Ctrl+Alt+T):

sudo aptitude reinstall xserver-xorg-video-intel 
sudo dpkg-reconfigure xserver-xorg

Install MESA:

sudo apt-get install mesa-utils

So, if you want to know what driver are using use:

glxinfo | grep -i render

Here how install the Linux video driver for Ubuntu:

After install the video driver is good make a actualization:

sudo apt-get update
sudo apt-get upgrade

NOTE: Sometimes the the privative drivers works better than the open driver, but try with them.

Here are a very good video tutorial to win more speed on Ubuntu
