Comment 11 for bug 295756

Thank you for uploading those files, now we can work on it.
First of all, I'm not exactly "pro" with this stuff, I got my experience from dealing with problems with my own hardware.

To make sure this is a bug here, we should get your configurations straight.
I see two problems here:
1.) Your xorg.conf is pretty stuffed, I'm not sure whether we get your system to run with this one.
2.) You seem to have installed the nvidia - driver for your Geforce, but to me it seems like the card used for your graphigs server is still the internal Intel graphics card.

I'd suggest the following things:

- Check in with buddies of you using Ubuntu or Linux, maybe they can help you with your problem
- Check in with your local Ubuntu forum, wiki or IRC. There are loads of nice people that can help you. Wiki articles that might be of interest for you are about building a xorg.conf, the nvidia drivers, etc. You can always upload your Xorg.0.log and xorg.conf to show them the relevant information about your graphics server.

Furthermore, you could try this (without quotation marks): "sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.mybackup" to make a working backup if your X server won't start. If anything goes wrong, you can restore it to what it was by "sudo cp /etc/X11/xorg.conf.mybackup /etc/X11/xorg.conf".
Now open your xorg.conf with "sudo gedit /etc/X11/xorg.conf" and change in Section "screen" # the value "device1" to "Configured Video Device" (note that you'll need the quotation marks this time) to get your nvidia - card with the nvidia driver to work in your graphic server.

Save the file, reboot your system. Maybe this'll do the trick.
I have to warn you though, this could make your graphic interface stop working, and I even don't know if your problem can be fixed that easy with a xorg.conf stuffed like yours.

You can always try to disable your internal Intel card via Bios (Check your manual how to do it) and give a fresh install of Hardy a try.
