Odd that the forum thread would not work. I will copy and paste the solution post here. For a full history of the discussion see the thread, "Nvidia 169.04 & 8800GT HELP!! ARGH!," in the Ubuntu forum, "Absolute Beginner Talk"
okay, now im reading a thread about build-essential recently being updated and breaking the 169 beta driver install. i been at this for 16 hours now.
here are my steps though mileage will vary.
1. fix software sources "Download from" usa to main server. update the resources. It is in Administration->Software Sources.
2. sudo apt-get install automake1.9 build-essential cvs libpango1.0-dev libgtk2.0-dev libgconf2-dev libglitz-glx-dev librsvg2-dev checkinstall libglade2-dev xserver-xorg-dev
3. uninstall in synaptic nvidia kernel common. Do a search. apply the changes before exiting synaptic
4. download the driver from nvidia http://www.nvnews.net/vbulletin/showthread.php?t=102509
5. log out of ubuntu after download is finished
6. hit ctrl+alt+F1
7. log into your username at the prompt in terminal
8. then in terminal cd /home/yourusername/Desktop
9. ls (just to see if your in the right directory where you downloaded the file in firefox)
10. sudo /etc/init.d/gdm stop
11. sudo sh NVIDIA-Linux-x86-169.04-pkg1.run (ignore the question or say no to kernel download during instal and have nvidia xconfig update the x)
12. "sudo reboot" in the terminal
13. add startup file to system->preference->sessions "nvidia-settings --load-config-only"
14. color correction is under system tools->nvidia x server settings. 1.240 for gamma correction under "x server color correction contrast 4096 sync to vblank"
15. sudo gedit /etc/X11/xorg.conf and add this line to it.
add this to this section "Option "NoLogo" "true""
Identifier "Generic Video Card"
Option "NoLogo" "true"
16. test in terminal glxgears
Hope this helps.
