I am also affected. Running Ubuntu 18.04 MATE i686 with 1 VGA and 1 DP.
The DP screen goes blank randomly for 1 second and then comes back.
Running kernel 4.10.17 from mainline.
Any fix for this sometime soon?
Thanks!

Sorry about not finishing the bisection. I was dubious about the
prospect of finding a nice clean patch to cherry pick in that drm-intel
branch. But this is superseded now by the upgrade of linux-generic-
hwe-16.04 to 4.15, which does not have the same issue.
I recommend closing this bug as
Would it be possible for you to test the latest 4.15 upstream stable
kernel?

Upgrading to kernel 4.17.2-041702 has solved the problem.

Thanks for all this good testing Tim and Joseph.
If I can help to keep things moving while Tim is travelling, let me know,
although might need a little guidance initially... if there are some good
instructions you can point me to on how to get the test kernel in and to

I can perform the bisect and build the kernels for you. Can you first

4.14-rc1 does fix the issue. So that just leaves 12600 commits to choose
from, according to git log v4.13-rc7..v4.14-rc1. I guess I would need to
recompile the kernel for each bisection iteration? Are we looking for a
drm/i915 commit? There's not quite so many of those (281).

We can perform a "Reverse" kernel bisect to identify the exact commit
that fixes this issue. We first would need to narrow down the versions
a little further.
Can you see if v4.14-rc1 fixes this issue:

To perform the bisect, we need to
I booted various mainline kernels from http://kernel.ubuntu.com/~kernel-
ppa/mainline/?C=N;O=D
* 4.11.12: works
* 4.12.14: fails
* 4.13.16: fails
* 4.14.2: works
* 4.14.13: works
* 4.15-rc7: works
So it would seem that the issue was introduced upstream in 4.12 and
fixed in 4.14.
