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.

Me, too. It's been plaguing me since about May also.
Is there a programmatic way to tell the thing is hung so
I can at least start up a daemon to kill and restart the
desktop when this happens?

    $ lspci | grep -i vga ; uname -a
    01:00.0 VGA compatible controller: NVIDIA Corporation GK107 [GeForce GT 740] (rev a1)
    Linux bach 4.10.0-35-generic #39~16.04.1-Ubuntu SMP Wed Sep 13 09:02:42 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

None of my logs have anything interesting preceding the forced reset.

Oh, another little thingy: after a forced reset, the auto-hide feature of the
system tray fails. It requires another reboot to clear the problem.
