You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run nvidia-xconfig as root), and restart the X server

Question

Im using Kubuntu 13.04 64-bit on my Dell Inspiron 17R laptop.

$ lspci|grep VGA:
    00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
    01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 650M / GTX 660M LE] (rev a1)

I tried to install NVIDIA drivers, firstly, from System/Additional Drivers but with no effect, then I did:

sudo apt-get purge nvidia* 
sudo apt-get autoremove nvidia-* 
sudo apt-get autoclean 
sudo apt-get autoremove 
sudo apt-get clean 
turned off all Additional Drivers from System/Additional drivers

sudo apt-get update && sudo apt-get dist-upgrade -y 
sudo add-apt-repository ppa:bumblebee/stable 
sudo apt-get update 
sudo apt-get install bumblebee virtualgl linux-headers-generic bumblebee-nvidia

restarted my laptop

sudo apt-get install kde-window-manager 
sudo apt-get install mesa-utils

and then tried:

# nvidia-xconfig nvidia-xconfig: no command found

So I did:

# apt-get install nvidia-common

but again .... :

# nvidia-xconfig
nvidia-xconfig: no command found

after all this, when I tried:

nvidia-settings

it showed me AGAIN: You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run nvidia-xconfig as root), and restart the X server

Help!

Solution

It seems you didn't actually install the driver. Have you tried:

apt-get install nvidia-current

before running nvidia-xconfig?

Ok, tried it, now I can run nvidia-xconfig but even if it tells that it created a xorg.conf file, when I run nvidia-settings I see my message again: You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run nvidia-xconfig as root), and restart the X server and cannot plug in my monitor :(
