Ubuntu – Install the correct Nvidia driver version for NVIDIA CUDA Toolkit


I have installed Ubuntu on, but now I am trying to install NVIDIA CUDA Toolkit for the GPU. When I install it, it says that there is no driver found, so I have tried to install the driver, but I don't know why after installation, the system not coming up. Maybe it is because of the wrong version of the driver.

When I tried to detect the driver version using sudo lshw -C display , it showed this information:

But here it doesn't say that what is the product name of the driver, and also when I go Software & Updates -> Additional Drivers, then it says NVIDIA Corporation: Unknown.

What should I do?

  • Sorry about posting this as an answer, I'm not able to post a comment to ask you this. Can you show the output of sudo lspci | grep -i nvidia? That might show what GPU it is.

    edit: I don't think this is a duplicate. the output of lshw would typically have the name of the GPU, which you could use to install the right driver. Here's what it would usually look like:
