Alternando entre as versões do driver nvdia em 16.04

Question

No momento, estou executando propriety nvidia drivers 361.42 no Ubuntu 16.04

$ dmesg | grep -i nvid
[    4.233238] NVRM: loading NVIDIA UNIX x86_64 Kernel Module  361.42  Tue Mar 22 18:10:58 PDT 2016

O cartão em si é um GTX-960

01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1) (prog-if 00 [VGA controller])

    Kernel modules: nvidiafb, nouveau, nvidia_361

Infelizmente, um software que estou usando reivindica um bug no driver faz com que seu software falhe e me pediram para fazer o downgrade do driver para 352.79.

Ele não quer simplesmente instalar o apt-get nesta versão, no entanto:

Como posso fazer o downgrade com segurança para esta versão do driver? Eu não posso simplesmente remover todos os drivers da nvidia e reinstalar porque o nouveau parece não funcionar com o meu hardware (eu tive que instalar o Ubuntu como a versão do servidor e depois convertê-lo para um desktop mais tarde).

No Ubuntu 16.04 nvidia-352 é apenas um pacote de transição para nvidia-361 .
Felizmente, nvidia-352 está disponível no PPA dos drivers da GPU proprietária.
Faça o download dos seguintes pacotes nvidia-352.79 realated do PPA:

libcuda1-352_352 .79-0ubuntu0 ~ gpu16.04.2_amd64.deb
nvidia-352_352.79-0ubuntu0 ~ gpu16.04.2_amd64.deb
nvidia-libopencl1-352_352.79-0ubuntu0~gpu16.04.2_amd64.deb < br> nvidia-opencl-icd-352_352.79-0ubuntu0 ~ gpu16.04.2_amd64.deb

Mas primeiro você deve verificar se os últimos drivers estáveis nvidia-364 podem resolver o problema.

Remova os drivers da NVIDIA 361 - abra um terminal e execute:

sudo apt purge nvidia*  
sudo reboot  

Selecione a entrada do menu do Ubuntu e pressione a tecla E .
Adicione nouveau.modeset=0 no final da linha linux.
Pressione a tecla F10 para inicializar no sistema operacional.

Importante: Defina um Espaço entre o último caractere na linha linux e nouveau.modeset=0 .

Quando a tela de login aparecer, pressione Ctrl + Alt + F1 .
Digite seu nome de usuário e senha e, em seguida, execute:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt install nvidia-364
sudo reboot

Caso esses drivers não funcionem - abra um terminal e execute:

sudo apt purge nvidia*  
sudo reboot  

Selecione a entrada do menu do Ubuntu e pressione a tecla E .
Adicione nouveau.modeset=0 no final da linha linux.
Pressione a tecla F10 para inicializar no sistema operacional.

Importante: Defina um Espaço entre o último caractere na linha linux e nouveau.modeset=0 .

Quando a tela de login aparecer, pressione Ctrl + Alt + F1 .
Digite seu nome de usuário e senha e, em seguida, execute:

cd /<path-to-the-folder-which-contains-the-.deb-files-you-have-downloaded-before>  

sudo dpkg -i libcuda1-352_352.79-0ubuntu0~gpu16.04.2_amd64.deb
sudo dpkg -i nvidia-352_352.79-0ubuntu0~gpu16.04.2_amd64.deb  
sudo dpkg -i nvidia-libopencl1-352_352.79-0ubuntu0~gpu16.04.2_amd64.deb  
sudo dpkg -i nvidia-opencl-icd-352_352.79-0ubuntu0~gpu16.04.2_amd64.deb  

sudo reboot  

Nota: Caso você receba um erro de dependência, execute apt install -f após cada erro.
