I haven't verified this yet, but it looks from the XOrg log like these
systems are booting into dual head (with the SVideo out on head 2),
2128x800 total. That width over 2048 is probably what's causing the
problem. I did "lose the mouse" on one, and suspected a "phantom head."
I went to System
I'm installing fresh Ubuntu 16.04, I will be trying the latest kernel
4.9 rc-6 to see if this is fixed.
I have a AMD A10-8700P Radeon R6, 10 Compute Cores 4C+6G × 4.
I can see there are a whole lot of AMDGPU commits in upcoming linux-
next. Maybe kernel 4.10 will finally solve this important
Please update the bug description to clarify if the machine with the
faulty HDMI port is the one with a capped resolution.
I experienced a similar issue recently. In my case it was a poor
connection on the HDMI plug limiting the available resolutions. The fix
for me was to plug in a fresh HDMI

Title:
nvidia driver causes blank screen
To manage
Excellent point. However I did not explain myself in that we do still
plan on providing users with the means to set an arbitrary fake
resolution. Whether or not we add common fake resolutions like 1024x768
to the modes list is all this bug needs to be about.
I would like to say such fake

Dell latitude e7450, Ubuntu 14.04 LTS.
Swapped disk from latitude e7450 with faulty HDMI port as a quick fix
while it gets repaired/replaced under warranty. "Pleasantly" surprised
to find the screen resolution capped abysmally low and neither video out
port working.

Hmm - so I'm not sure what's going on here. I started bisecting v4.1 ..
v4.2.8 and I couldn't find a working version in 6-7 bisects and when I
checked rest of the commit set in the bisect, it couldn't find any
commits to drivers/gpu?!
So I decided to test Ubuntu mainline kernels a little bit more
So I downloaded some kernels from http://kernel.ubuntu.com/~kernel-

While keeping the Xenial HWE stack on Ubuntu Trusty (14.04), I tried
various installed HWE kernels.
It seems it really broke with the Wily kernel (4.2.0.42.34). The Vivid
kernel (3.19.0.74.56) has survived multiple resume cycles, while Wily
instantly created the problem.

I think the priority is incorrect, and hopefully not based on the
scaling comment, which I think is maybe one use case, but not the most
important one:

lowest quality settings.”
I can argue that the same can be said for e.g. youtube videos.

This is just a display problem - a snapshot is correct, so it really
looks like a radeon driver problem, instead of an xorg problem.
The wrong colors are always different, so every cycle produces a
different result. For a photo as background it almost looks like modern
art ;-)

Public bug reported:
When waking up the system from a suspend-resume cycle, the display most times
shows distorted colours.
As a workaround one can switch to the linux console (VT) and back to fix the
display.
Alternatively triggering DPMS also fixes the problem (xset dpms force off ;
