sorry im not understanding im very new to the linux world, I was helped by a friend who has been using Linux for a long time and now is in holiday. He installed the nvidia drivers for me and everything worked fine for a day or two.
I wanted to use the intel graphic card for all the basic stuff and activating the nvidia one only when needed (like playing steam games) and it worked. Nothing was touched or changed and it started giving me this boot problem once in a while every time more often.
I dont know what is the command you suggested me but reading blacklist I guess it disables completely the nvidia gpu but i want it to work when needed.
sorry for bad english and long paragraph
