Hi,
I am using the nouveau driver because its really great, even better than the
official ndivida driver. i get better rendering results with nouveau than with
the original nvidia driver what is a shame for nvidia, but thats another topic.

The only problem that I have currently is that nouveau leads to make my monitor
goes off randomly and only a complete system reset helps me out. I have tested
with another laptop and the same monitor, I didnt see the same problem. Also I
have changed the port and the cable, so that I guess its not the cable either.

I have tested with the original nvidia linux driver and I didnt see the monitor
going off again. So I guess its because of nouveau. When my monitor goes off I
see also the gpu fans runs in full speed what is strange because the system is
not running any gpu related apps.

my system configuration: 

$ lspci | grep -i vga
01:00.0 VGA compatible controller: NVIDIA Corporation GP104 [GeForce GTX 1080]
(rev a1)

$ uname -a
Linux rs.com 4.10.13-1-ARCH #1 SMP PREEMPT Thu Apr 27 12:15:09 CEST 2017 x86_64
GNU/Linux

My monitor is the Asus Curved PG348Q ROG

I get also strange entires in the bootlog. My monitor went off recently so that
I post a log before the monitor went off and the second log is after the
monitor went off (after a system reset). Hope this can help somehow.

FIRST LOG (BEFORE MONITOR WENT BLACK)

AFTER SYSTEM RESET:

I would really like to find a solution as soon as possible coz it blocks my
work.
