Configuring KMS (Kernel Mode Setting) on Ubuntu Koala Karmic (9.10) for New Intel video driver

KMS (Kernel Mode Seting) :  can be used in the kernel 2.6.30-2 (or newer). Since the kernel 2.6.30-10.12 KMS is enabled by default, if the kernel version of the old versions can't. Require must be implemented is as follows:
    
 Intel drivers-2.7.99.1 or later (note that this is enabled by default UXA). Or the newer-intel from the xorg-edgers PPA. 


Turn on KMS in your kernel module
to turn on KMS for  one boot, add kernel parameter i915.modeset = 1, and  boot your system.
and to turn on permanently you can kms config in directory /etc/modprobe.d/i915-kms.conf  by type :

$ sudo su
$ gedit /etc/modprobe.d/i915-kms.conf

and add this line :


options i915 modeset=1
and reboot your system by type :

$ reboot 

If there have problem, turn off i915-kms.conf by type

$ gedit /etc/modprobe.d/i915-kms.conf 

and replace into

options i915 modeset=1 to options i915 nomodeset

To set KMS manually any other way by type :

 $ sudo /etc/init.d/gdm stop
 $ sudo rmmod i915
 $ sudo modprobe i915 modeset=1
 $ sudo /etc/init.d/gdm start

Happy Testing...!!
