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?
