Comment 3 for bug 1734277

Hello.
In order to work around this problem, we need to install the proprietary NVIDIA driver. (384.90)

This automatically displays full error messages on the screen. ( https://pix.tdct.org/upload/original/1512478780.jpg )
it can be seen that the computer can shut down almost normally after waiting 5 minutes.

The next start is no longer in wayland session but we must also wait 5 minutes when stopping.
