I’ve strictly followed the CUDA 8.0 installation process mentioned here: http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html
but I found it doesn’t describe the X server issues, because when I execute it in my Ubuntu16.10 environment it report I need stop X Server before installing CUDA8.0,
The following is the error message:
Installing the NVIDIA display driver…
It appears that an X server is running. Please exit X before installation. If you’re sure that X is not running, but are getting this error, please delete any X lock files in /tmp.
= Summary =
Driver: Installation Failed
Toolkit: Installation skipped
Samples: Installation skipped
Question one: Can anyone who could add steps on how to stop the X server into the CUDA8.0 installation guide?
Question two: Who could help me on how to stop the X server before the official guide release? I use the steps mentioned here:
sudo service lightdm stop
sudo service lightdm start
But I couldn’t restart the GUI system after following it, I don’t know why. Who could help? Thanks advance.
