I have recently installed ubuntu 11.04 in a dell inspiron 17R and everything is fine except that the system doesn't recognize additional drivers. It says no proprietary drivers are in use on this system.

Why do you need to install additional drivers? Intel cards are supported by default in Ubuntu. –  Lekensteyn Jul 25 '11 at 16:12
    
@Lekensteyn Turn that into an answer before I do ;) –  Oli Jul 25 '11 at 16:28

You can use the xorg-edgers repository of experimental drivers to update the drivers for your video card. Because the drivers are not guaranteed the experimental operation, can solve problems but also created new problems, but you sure are using the latest release of the same.

I own a laptop with this graphics card and recently updated the drivers for this repository, where there was no problem. If you want to perform the update run the command

sudo apt-add-repository ppa:xorg-edgers/ppa && sudo apt-get update && sudo apt-get dist-upgrade -y

And restart your computer. After the restart the driver will be updated.

Your video card also has the technology SNA - Sandy Bridge New Acceleration Architecture that improves some acceleration features. After updating the driver to use this feature enter the commands

sudo apt-add-repository ppa:sarvatt/sna-intel && sudo apt-get update && sudo apt-get dist-upgrade-y

Use this at your own risk, please understand that PPAs can break your system.

The additional drivers tool is there for proprietary (that is non-free, closed source) drivers that can't be distributed on the Ubuntu CD.

Intel graphics drivers, including those for the Intel GMA 4500MHD in your laptop, are part of the default Linux Kernel and X should have its counterpart installed by default (the xserver-xorg-video-intel package).

In short: you shouldn't need to do anything. It should work out the box.

If it's not, you might want to start another question, detailing the problem a little more explicitly.

Intel created a gui that updates more than what you get with backports.

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

You can refer to this post for more information.
