Thanks for considering my problem...

You need to install:

linux-backports-modules-alsa-maverick-generic

To get sound working. Can you expand on "dvd rom is not able to detect"

Thanks

@actionparsnip: Sir surely i will provide you with more information regarding dvd not working but first i had to install ubuntu 10.10 in my lappy i will do it in coming days as my exams are going on...
I will be providing you with full details of the lappy...
Sir what about my graphic card my graphic card is switchable can you provide me with some help regarding this issue my graphic card is
1gb nvidia gt 320m cuda...
Sir i also heard about the linux operating system customize to their own lappy or pc.
I had read about this in Digit magazine the operating system will compile itself and all the unrelated stuff's are not used or installed and the pc will boost because it has that much feature as it required...

The installed OS is external to how you mean by "dvd rom is not able to detect" I need to understand what you mean by the phrase so I can troubleshoot. It could have many meanings so we need the one YOU mean.

In ubuntu there is very little compiling at all, it uses binaries so installs quick.

Did you get the package installed?

if you have internet connetion, when you click on any song then ubuntu automatically updates drivers and then sound comes..............so u need internet connection.......

Sir my problem is solved of dvd, i had installed ubuntu 10.10 64bit os, and it is detecting my dvd rom. Sir i want to ask you a new question that when i try to install ubuntu in that i had selected option of manually selecting the partition in that only 4 partition i had able to see, why is it so, due to this i had many problems in installing ubuntu but i still manage to install it perfectly...

You may only have 4 primary partitions on a disk, if you need more you must set one as an extended partition and you can set as many logical partitions as you wish within that.

I had came across another problem. Whenever i use my laptop on my battery mode my dvd rom does not open when i click on eject button, but when i plug in the power then my dvd start's working...
I don't know why this problem persist did any one has any idea please suggest...
