Your system is not currently using hardware acceleration for graphics - to enable this, you will need to try to update the drivers. I know of four options, only one of which has ever worked well for me.

Before you use any of these options, you may also want to run sudo apt-get install linux-firmware-nonfree - this will load the firmware for which there is no source code.

Option 1 (the only one that worked for me) Use the graphics drivers from oibaf:

sudo add-apt-repositoryppa:oibaf/graphics-drivers

sudo apt-get update

sudo apt-get upgrade

More information can be found at launchpad

Option 2 - use the xorg-edgers. These can be found on launchpad, but they are not always entirely stable and may break your system

Option 3 - download and compile the official slick new and totally advanced intel drivers from 01.org. Before you do this, read about how to uninstall them!

Option 4 - in the software sources (open the dash and type software sources), the rightmost tab 'Additional Drivers' may have drivers that can work in your system. Again, you should review how to remove them, before you install them.
