После перехода на Intel (режим энергосбережения) в настройках X-сервера Nvidia ничего не отображается. Мне нужно активировать графический процессор сейчас, но я не могу его активировать.

I fixed this issue by installing another version of Nvidia driver. I am not sure about whether this error will appear again.
Your graphics isn't recognized.
I just reinstalled OS and mark "install third party software".
After that, do not install any other graphic driver. You will run on Intel choosen by Ubuntu. Nothing other works like this solution.
PS: When you reinstall, you can choose in Nvidia x server settings " Power saving mode".
Hope it helps.
