I experienced a similar situation with a fresh installation of Ubuntu Gnome on Dell XPS 15. I didn't install virtual box.
Details about my computer:
Processor: Intel® Core™ i7-7700HQ CPU @ 2.80GHz
Graphics: GeForce GTX 1050/PCIe/SSE2
Driver: Nvidia binary driver version 384.90; Processor microcode from intel-microcode(proprietary)
After running "prime-select intel" and log out, I couldn't log in again. When I tried to log in, the screen just blanked out and got back to log in screen after a few seconds. After I run "prime-select nvidia" in tty to restore settings, I can log in.
The solution on #11 didn't work for me. It successfully shut down the graphics, but I couldn't open GUI anymore and had to reboot to power up the graphics.
However, I did find some workaround if you just want to reduce the power consumption. Instead of shutting down the graphics, you may constrain the clock rate by using this method:

It worked on my computer and helped me to get rid of the annoying sound from GPU fan.
