I had the same error a few minutes ago. First I installed drivers for my video card from NV website and after I installed envy package. I seems that Ubuntu recommended me 177.80 driver version and envy recommended 173 version. So i tried to change and activate 173 driver version from envy with gdm started. Envy crashed and after restart ubuntu gdm started in a low resolution. I tried to fix this but without any success. So I followed the steps from envy site:
First I redownloaded the NV driver from their website (because after I installed it i removed the installer package), then I pressed Ctrl+Alt+F1 and I logged in with my user and password. After I logged in I make myself root by typing: "sudo su" and pressed enter key. I stopped the gdm by running the command: "/etc/init.d/gdm stop" After this I change location to my NV installer location and then run the following command: "sh NVIDIA_INSTALLER_NAME.sh --uninstall" After this I started the envyng with: "envyng -t" and I followed the menu and when I finished I rebooted the computer. Know it seems to recognized the NV driver (installed with Envyng - and everything works fine - except my screen refresh rate :|:|:| ) This worked for me. You can try it too, maybe will work. More information you can find at this location: http://www.albertomilone.com/envyngfaq.html#E If you can help me with my screen refresh rate please send an email at emilian [dot] serbanescu [at] yahoo [dot] com to provide you with more information about my display and the problem that I have.
