Re: NVAC "No Signal"

[Jeff Backus <jeff.backus-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Hi all,

My apologies - I'm trying to reply to a thread and the web interface 
doesn't play well with Mutt. I tried to hack it. Hopefully I didn't goof 
it up too much!

I am also getting a "No Signal" on the HDMI port when the resolution 
changes on boot. This is on an ION-based desktop. VGA is fine when the 
monitor is plugged in on boot, but is disabled if I plug it in 
afterwards. When the issue is observed, the X server appears to start up 
without issue. I can SSH in from another machine, set my DISPLAY 
accordingly, and then query and change resolution as if the monitor is 
behaving normally. However, monitor indicates no signal. Additionally, 
this affects both the kernel and the text console.

This is on a Fedora install. Issue was observed with kernels 4.8.4, 
4.8.13, and 4.8.15. I verified that kernels 4.5.5 and 4.7.9 work.

Additionally, this issue was observed with:
- Nouveau, version 1.0.12, I believe
- Version 340.98 of the nVidia binary driver found in the RPMFusion repo 
  (xorg-x11-drv-nvidia-340xx)
- Version 340.101 of the official nVidia binary driver, downloaded on 
  12/27/2016.

Re: information from nVidia - given that this affects both Nouveau and 
the official binary, I suspect that there is some confusion on the 
nVidia end. Perhaps a case of "mostly correct" documentation?

It looks like this bug is also related?
https://bugs.freedesktop.org/show_bug.cgi?id=98405

Have there been any updates on this since Peirre's Nov. 9th update?

Thanks!

Regards,
Jeff
