Nvidia Driver installs but does not work 3d acceleration

1. Please input the detailed title of your suggestion or problem
I installed the nvidia drivers for my nvidia 940mx by the system driver manager and also manually by the terminal, in both cases everything is installed but when I open the managed from nvidia, it shows message that the nvidia driver is not being used and requests that I Enable nvidia-xserver, I already tried to start this process also by the terminal but I continue without 3d acceleration.
