Fix Slow Graphics Performance on Ubuntu 13.04 + Intel GPU

Hello Linux Geeksters.

In this short guide I will show you how to fix the slow graphics performance, after upgrading to Ubuntu 13.04 Raring Ringtail, and using Intel GPU.

To fix the graphics problem, do this two things:

1. Create the /etc/X11/xorg.conf file:

$ sudo touch /etc/X11/xorg.conf

2. Open the newly created file in a text editor, with sudo privileges:

$ gksudo gedit /etc/X11/xorg.conf

3. Paste this:

Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "uxa"
#Option "AccelMethod" "sna"
EndSection

This is it. Enjoy.
