Não é possível obter o NVidia 9600GT trabalhando com o Kubuntu 14.04

Question

Problema: os drivers da Nvidia não estão carregando

Hardware: Dell T110

Placa Gráfica

root@madeye:~# lspci | grep VGA
02:00.0 VGA compatible controller: NVIDIA Corporation G96 [GeForce 9500 GT] (rev a1)

Pacotes Nvidia instalados

root@madeye:~# dpkg --get-selections | grep nvidia
nvidia-304                  deinstall
nvidia-304-updates              install
nvidia-current-updates              install
nvidia-libopencl1-304               deinstall
nvidia-libopencl1-304-updates           install
nvidia-opencl-icd-304               deinstall
nvidia-opencl-icd-304-updates           install
nvidia-settings                 install

Atualizei todos os pacotes após a instalação e instalação dos cabeçalhos do kernel

Quais outras etapas de solução de problemas eu preciso fazer? O que posso fazer para que o kernel reconheça a placa gráfica?

Como resposta de Terdon, se eu executar o comando, recebo a mensagem abaixo:

dthacker@madeye:~$ sudo apt-get install nvidia-kernel-dkms nvidia-xconfig nvidia-settings
Reading package lists... Done 
Building dependency tree Reading state information... Done 
Package nvidia-kernel-dkms is not available, but is referred to by another package. 
This may mean that the package is missing, has been obsoleted, or is only available from another source 
E: Package 'nvidia-kernel-dkms' has no installation candidate 
E: Unable to locate package nvidia-xconfig'

@terdon, usei este utilitário do artigo em que você me apontou:

root@madeye:~# ubuntu-drivers devices | grep recommended
driver   : nvidia-331 - distro non-free recommended

Eu, então, instalei o nvidia-331 e o utilitário de drivers restritos mostra que ele está sendo usado. O utilitário nvidia GUI ainda não tem opções visíveis para a configuração de vários monitores (atualmente há dois conectados à placa) e ainda estou recebendo erros no kern.log dizendo que o módulo de inicialização da Nvidia falhou.

Ainda trabalhando para uma solução ...

Saída de apt-get install nvidia-driver :
