I have choppy video and my windows are choppy when I move them around. Also when my PC turns off monitor it does not turn off normally but like the cable was unplugged. I guess I need to install a driver for my new 'graphics' chip. Can someone please provide the 'best' way of installing graphics drivers for my Celeron G1820 CPU.

Here is what I get from lspci:

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)

I can provide any additional info if needed.

+----------+----------+----------+----------+----------+------+

You should Install xf86-video-intel a binary package containing driver for all Intel GPU Chipsets.

Because I don't know the exact nature of your problem (whether it is the driver, Kernel module, or Xorg Configuration) I cant recommend any additional steps. But it's worth mentioning that Xorg config file and modeset in Grub are also places to look at.

Add Intel Repository :

sudo sh -c 'echo "deb https://download.01.org/gfx/ubuntu/12.04/main Ubuntu 12.04" >> /etc/apt/sources.list.d/intel-graphics.list'

Then download and install the GPG key via 2 commands:

wget https://download.01.org/gfx/RPM-GPG-KEY-ilg -O - | sudo apt-key add -

and

wget https://download.01.org/gfx/RPM-GPG-KEY-ilg-2 -O - | sudo apt-key add -

install Intel Graphics Driver:

sudo apt-get update; sudo apt-get install intel-linux-graphics-installer
