How I can install NVidia 610M graphic card drivers in a Lenovo Thinkpad Edge E430 with Ubuntu 18.04?
Download your NVIDIA 610M drivers from https://www.nvidia.com/download/driverResults.aspx/104284/ which also includes your installation instructions.
Once you have downloaded the driver, change to the directory containing the driver package, make it executable with
sudo chmod +x NVIDIA-Linux-x86_64-367.27.run , and install the driver by running
sudo sh ./NVIDIA-Linux-x86_64-367.27.run
One of the last installation steps will offer to update your X configuration file. Either accept that offer, edit your X configuration file manually so that the NVIDIA X driver will be used, or run
sudo nvidia-xconfig .
