my notebook is using both intel integrated and external GPU with two operating system ubuntu and win10.
On ubuntu system,it cannot switch to use nvidia Geforce GTX 960M,it block me from using cuda.
I have tried to reinstall nvidia drivers multiple times.I have tried installing from both command line and "Software & update"app.
Right now i have driver version 440.59.
I am just a student and hard to find many helps from my side.
sincerely expect your help.
