For installing the ATI driver I have used the Restricted Drivers manage and the rest of the work I mean the detecting of everything was fine at the time of reboot. After shutting down the switchable graphics.
One thing I like to mention that I have experienced flickering while using certain output modules. May be it is a bug in the drivers. I will suggest you to try either the Xv output module in the VLC or try to use Metacity in place of Compiz.

For avoiding the flickering problem, you can follow the steps given below
First you have to make a copy of xorg.conf - I prefer using the days date in this format (YYMMDD)

Code:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup<date>

After that open the xorg.conf for the purpose of editing.

Code:

sudo gedit /etc/X11/xorg.conf

After I have added the following code to the Device section under the driver

Code:

Section "Device"
	........
	Option	    "VideoOverlay" "off"
	Option	    "OpenGLOverlay" "on"
	Option      "TexturedVideo" "off"
        .........
EndSection

Now save the file and restart you system hope this will work.
If this changes breaks, you X-boot in the recover command line from the Grub then do the following

Code:

sudo cp /etc/X11/xorg.conf.backup<date> /etc/X11/xorg.conf

If you cannot remember the name of the backup, or you want to switch to a different xorg.conf then do a directory listing that will list all the files.

Code:

cd /etc/X11/
dir

Now reboot.

Hopefully this helps!

I have successfully installed ATI driver on my T400 ubuntu 9.10(karmic), with the full 3D accelerate and there is no GUI lagging.
Below are the steps through I have done so.
1. Use the ATI propriety driver ATI drive installed 9-12-x86.x86_64. But, ati-driver-installer-9-8-x86.x86_64.run does not support 9.10 and cause the problem

Code:

> sudo sh ./ati-driver-installer-9-11-x86.x86_64.run

2. After completing the installation in GUI, then use

Code:

> sudo dpkg-reconfigure xserver-xorg
> reboot

3. Now the ATI driver successfully installed with 3D acceleration. But the user interface suffers a lot of problem while opening and minimizing the window.

4. Adding a PPA to your Ubuntu operating system.

Code:

> sudo add-apt-repository ppa:launchpad-weyland/ppa

5. Add /etc/apt/sources.list these sources:

Code:

> sudo apt-get update
> sudo apt-get upgrade

this will solve the problem

Thank you for your reply

These steps, the procedure you have mentioned is a bit long and complicated, and one more thing it require the knowledge of using commands.

But I want to say one thing that this procedure works and I am getting a perfect graphical user interface.
