===== Are the Nvidia Geforce 9600GT supported on Kubuntu 9.04? =====

Short how to:
  - dowload driver here: http://us.download.nvidia.com/XFree86/Linux-x86/180.51/NVIDIA-Linux-x86-180.51-pkg1.run
  - press ctrl-alt-f1
  - login using you're username and password
  - do 'sudo /etc/init.d/kdm stop'
  - cd to the directory where you downloaded the driver
  - there, do 'sudo sh NVIDIA-Linux-x86-180.51.pkg1.run' and follow instructions (it's mostly just a matter of pressing ok and yes a bunch of times)
  - when the installer is finished, do ctrl-alt-f7 or 'sudo reboot'


----

one thing that I used to have to do is add the boot options noapic and nolapic.  You can do this at boot time by going to the grub menu to see if it works...if it does, then you can add it as default...I'm grasping at straws here, but it is worth a try...if you need help on how to add these, let me know...
----

I reviewed the thread -- I don't see a couple of things mentioned, that might make a difference:

1. Before running the downloaded installer, you should have installed the linux-headers-`uname -r` and build-essential packages.

2. After running the downloaded installer, and BEFORE issuing the startx command, you should run the
<code>
sudo nvidia-xconfig
</code>
utility.


If you're not sure about whether you did these, back up your xorg.conf file 
<code>
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak28apr09
</code>
and then run through the driver installation process again and make sure not to skip the
<code>
sudo nvidia-xconfig
</code>
step.

----

Are you exiting the GUI with Ctrl-Alt-F1, and shutting down the X server with
<code>
sudo /etc/init.d/kdm stop
</code>
before you run the installer?


----

When you try again, this is how I do it: 

  - Download the nvidia driver you want.  leave it in your home directory.
  - sudo apt-get install build-essential linux-headers-'uname-r'  (not sure on the 'linux-headers')
  - boot into recovery mode, and drop to root shell
  - enter cd /home/username
  - enter sh NV {and press tab}
  - go through the install process, and allow the installer to update your xorg.

a couple things...I know that I shouldn't use a root shell on my /home directory...but I have never had a problem doing it this way...also, the installer will throw a few warnings, but again, it always works.

works for me...
