How I got my Hardy Nvidia problems sorted
my Hardy upgrade went well, and all the trouble started when I wanted to enable the cool new visual effects. The error message was that the Nvidia drivers were not installed. No problem I thought, lets go to System - Administration - Hardware Drivers and enable them there.
That is when I was dumped in driver hell!!
I only had 800*600 vesa, and it killed my keyboard layout. In trying to fix the video problem, I killed my sound as well.
With lots of work, everything is working now thanks to the following kind souls who posted the help.
What I did to get it sorted:
1) Found out that I was using the wrong kernel. I wanted 2.6.24-16-generic, which was also enabled in my synaptic, but grub menu.lst had 2.6.24-16-rt in first place. So I needed to edit the menu.lst to boot the right kernel.
2) To fix the sound, i used the following guide.

3) To fix the keyboard was as simple as going System-Preferences-Keyboard and clicking on the Layouts tab and filling in the details.
4) To fix the Nvidia was a bit more tricky. My Geforce 6200 now works due to the following :
