How to enabled nvidia accelerated driver in Ubuntu on my Toshiba Laptop

First of all I want you know some useful links for install Ubuntu:

It's so easy to install Ubuntu on your desktop or laptop that you do not need read the links above. BUT for some Laptop you may need some tricky configuration setup, like my toshiba satellite pro 6100 and TE2100. Both them have same video card which is GeForce4 420 Go.

1. When you install, you could select the second options, something like safe graphice config mode.(forgot the exactly titile).

2. After restart, Ubuntu start with lower resolution mode with nv or vesa driver, not nvidia driver.

3. You can change the driver to nvidia from System->Administration ->Screens and Graphics OR you can enable your accelerated driver from "Restricted drivers manager". But when you restart the X, you maybe got the blank screen or black bar on the right hand side of scrren.

HOW TO FIX THIS PROBLEM? That's what I want to say here.
Before you restart your Ubuntu, you have to add some cofig to your xorg.conf file.

sudo gedit /etc/X11/xorg.conf

comment out
 # Load 'GLcore"

add the following line to the Device section:
Option "UseDisplayDevice" "DFP-0"

Another change is :
sudo gedit /etc/default/linux-restricted-modules-common

change the line that reads "DISABLED MODULES="" to read DISABLED MODULES="nv vesa"

4. restart your laptop, got black bar on the right hand side or small image. That's fine, at least your got your nvidia driver running, just the system recognized your screen si 969x768 instead of 1024x768.you can find who to fix here
if you have 1600x1200 screen, you can see  How to fix it?

if you don't have install ghex, you don't have to.

> sudo nvidia-settings
save your original EDID.bin to /path/to/
> cd /path/to
>xxd <edid.bin >edid.hex
>vi edid.hex
The horizontal resolution is safed in the bytes with the offset 56(Hex:38) and 58 (the upper four bits) (Hex:3A) In the original EDIT these bytes were C9 and 31 (0x3C9 = 969) I changed them to 00 and 41 (0x400 = 1024).

>cp edid.bin edid.bin.org
>xxd �Cr <edid.hex  >edid.bin
> sudo cp edid.bin /

5. add option in xorg.conf file
Option "CustomEDID" " DFP-0:/edid.bin"

That's all, you can restart your Ubuntu with accelerated driver which is the version in Ubuntu.

Do you want update to the latest version of nvidia video card driver, see you next time.

BTW, the attached file should be edid.bin, so you have to change the name from edid.txt to edid.bin after you download.
