Ubuntu 16.04 - VSync não ativado, rasgando a tela

Estou a usar:

• GTX950M
• Gráficos de chipset Intel integrados da i7-6700
• Ubuntu 16.04

glxgear detecta cerca de 16000 fps.

Estes são meus drivers da nvidia:

aptitude search nvidia | grep ^i 
i   nvidia-361                      - NVIDIA binary driver - version 361.42     
i A nvidia-opencl-icd-361           - NVIDIA OpenCL ICD                         
i A nvidia-prime                    - Tools to enable NVIDIA's Prime            
i A nvidia-settings                 - Tool for configuring the NVIDIA graphics d

Essa é minha nvidia-config:

E a configuração do Xorg:

    Identifier "intel"

    Identifier "nvidia"
    Device "nvidia"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"

Mas vejo muito rasgo no chrome, vídeos, etc ...

Qualquer ideia?

Não me lembro do link em que obtive essas configurações. Também tenho Intel i7-6700, mas tenho um pouco mais recente de GTX970M. Após muita tentativa e erro, essas configurações funcionaram para mim (com as configurações antigas comentadas):
