Not having much luck with the Distro
forums on this issue so I thought
I'd ask for advice here.
I've been running Ubuntu 14.04.4 for some time on Intel Core
i5 GFX
without any issues. My display is HDMI from the PC to an
Onkyo A/V
receiver then to a Sony KDL-XBR6.
Core i5 is a bit vague; to know what graphics generation you
run,
could you provide the output of:
sudo cat /sys/kernel/debug/dri/0/i915_capabilities

Also, since it might be a kernel issue,
the kernel version would be
nice to know too (uname -a).

Intel Desktop DCP847SKE NUC with Intel Celeron CPU 847 @ 1.10GHZ
To explain the differences between my OP about Core i5 and tests
on Celeron. My production PC with the problem is a Core i5, buy I
took it back to Ubuntu 14.04 LTS until this is resolved. I setup
a Celeron NUC to use to help solve this issue. Since All my PCs
have Intel GFX and all have this problem using the Sony TV and
Onkyo receiver on 16.04, the NUC was the easiest to setup and
leave alone until the problem is resolved.

I got an update from Ubuntu for the xserver
intel driver. After installing and rebooting, I find that while
I still have some problems, they are reduced. I can go for 5-10
minutes before a blank screen and the horizontal line noise is
reduced but not gone.
The log for the apt upgrade is as follows:

When I try a fresh install of 16.04.1,
I get a display that blanks out
for 3-5 seconds at random times depending on what is being
displayed
at the time. I also have small amouts of video noise that
is random
horizontal lines about 1 pixel tall scattered through the
page.
I noticed that 14.04.05 uses X server 1.17.2 and 16.04.1
uses 1.18.3.
When I do the command xrandr --verbose I see some small
differences
between 14.04 and 16.04, but it's things like 2 digits
displayed
instead of 1. i.e. 60.0 vs. 60.00. I'm only concerned with
1080P HD.
I've tried this on different computers all with Intel GFX.
same results.
This does not occur on other monitors or TVs.
I'd blame it on Sony and Onkyo if they didn't work so well
with
Windows, all versions, and Ubuntu all versions except 16.04.
It's almost like the auto detection software in the newest
version of
X is off just enough to make my display flaky. Kind of like
the old
analog CRT TVs that were sensitive to small tweaks to the
horizontal
and vertical adjustments.
Any help would be appreciated.
Kind regards, David Weinehall
