After the latest kernel upgrade from Ubuntu, my nvidia card drivers suddenly stopped working and I was back to native 640x480 and couldnt get out. Why? BEcause at 640x480 the "Screen resolution" window height is larger than the viewport!
I had to use the tab controls and "guess" which button would be "Apply". Hooray for brain dead GUI errors.
After setting resolution to a respectable 1024x768, I googled to get the envy package to get my nvidia fix. Envy worked like a charm installing the nvidia drivers... But then I realized that none of my applications could detect the nvidia drivers.
Since I wasnt intent on playing games at that time, I let the issue rest for almost 2 weeks.. During that time, VmWare Workstation refused to permit direct3d rendering in any guest. This in itself didnt matter much - I typically prefer to RDP / VNC into the guest anyways.
Today however, I had the urge to play UT and it crashed saying no display device (!).
After reinstalling various flavors of nvidia drivers, I eventually stumbled upon the realization that glxgears complained about not being able to open /dev/nvidiactl unless it was run as root.
It turned out to be a f***ing permissions issue.
Long story short, on the next Ubuntu kernel upgrade that breaks the nvidia drivers, reinstall nvidia driver, dont bother with EnvyNG and make sure you "chmod g+r,g+w,a+r,a+w /dev/nvidiactl".
... and then bask in the awesomeness of your Nvidia card and the hackety hack that brought it back to life!

Oh-so-happy economics... NOT!
First, a history lesson that we have been cursed to repeat: PBS documentary about the stock market crash preceding the Great Depression of 1929.
Then, the highly technical, yet layman friendly Failure to deliver (FTD).
The dot com bust of 2001 spawned this blistering site that first predicted, then chronicled failed businesses. Its a beautiful mix of pessimism and schadenfreude, but dont be fooled into thinking that what they are stating isnt true or that it never happened. It is true. It did happen. There is a downside.
