Ubuntu not properly detecting any of my laptop's built devices (HP DV4000)

Hello. First of all I apologize if my post is in poor format. This is my first ever post.

From what I can tell Ubuntu seems to be detecting things like my:

Video Card
Sound Card
Wireless (not working have tried downloading the suggested packages for the broadcom wireless card to no avail)

All of these and possibly others seem to be detected as generic. I have sound and my display is ok. But I am lacking tv out functionality.

My evidence of my devices being detected at generic is my xorg.conf file (which I generated using some steps in another forum):

A little information about my setup. I am running Ubuntu 10.10 and it was installed using wubi on a partition that also has some windows programs.

I know that some programs are able to see the devices properly on Ubuntu as I downloaded a package called Sysinfo which is able to identify my video card as i915 and wireless card as the proper broadcom model.

As far as steps to take I am not very familiar with Ubuntu programs but have learned a little about using terminal and should be able to follow whatever steps are advised.

Thank you very very much for all your help.

P.S. - I am prepared to reformat the entire hard drive and install Ubuntu on a fresh partition but this would be a rather large undertaking so I would prefer to find an alternate solution or at least try other steps before resorting to this step.

P.P.S. - I have posted a couple other things from my system at the end here I am not sure if it is relevant but was requested in resolving the Broadcom Wireless card issue in another post.

You should post the results of your command using [CODE] [/ CODE] (without a space between the / and CODE). it would be easier to read. (also I prefer
 lsmod | sort
, but maybe that's just me)

About your wireless problem, I see that you have the BCM4318, did you try the procedure explained here :

About your video card, what exactly is your problem?
if you want some help on that, you should post the result of
lspci | grep VGA
good luck!

Hi annihilation_ca, Welcome to LQ. It sounds like you're asking for help with your wireless? Your lspci output tells us you have the bcm4318 chip and this requires the b43 driver and firmware. There is more here:

Good luck. ;-)

Ok, thanks very much for the replies. I appreciate both the links you folks have given. Those exact solutions did not work for me but I was able to get my wifi card working using the following 2 links describing the Ndiswrapper method, in case anyone else using an HP Pavilion dv4000 can potentially benefit:

when I had to choose which sys and inf files I used: bcmwl5

I greatly appreciate the help once again. I think now that my problem is exclusively getting my video card's tv-out functionality working I will post a separate topic and mark this post as solved.
