I have Ubuntu 16.04.3 LTS with nvidia-384 and nvidia-prime packages installed using PPA ppa:graphics-drivers. After installation, my default desktop manager changed from gdm3 to lightdm, and I fixed it by reinstalling gdm package. After then, my system worked fine using nvidia drivers (except the fact that after resuming the system, my background goes white). Later, I wanted to use nvidia PRIME to switch my Intel card, however, after doing so, I could no longer login my Gnome Session. I had to use prime-select nvidia from TTY to be able to login.

My question is how can I fix this issue? Is it a bug related to GNOME (most likely), if it is so, is there anything I can do?

PS: The same issue happens with 17.04 as well, and Unity has never exhibited such behavior.

I have the same issue with Gnome Ubuntu 16.04. I think I found a workaround.

At login open terminal:

  1. sudo prime-select intel
  2. systemctl restart display-manager
  3. Log in and go.

I am not sure if the power savings are there yet. Trying to confirm.
