["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

boukeas, at your earliest convenience, could you please test the latest
upstream kernel available from the very top line at the top of the page
from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release
names are irrelevant for testing, and please do not test the daily
folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  Screen periodically goes black for a second

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I am using Ubuntu 14.04.3 on a HP ProBook 430 G2/2246. It is often the
  case that my screen goes black for a second and then recovers. It is
  my impression that this only happens when the computer has been idle
  -- even for a very short time -- so I have disabled screen locking and
  dimming and I have also removed the gnome-screensaver package, yet the
  problem persists.

  I took a look at /var/log/syslog and discovered an identical set of
  error messages (dump traces, mainly) for every time this happens. I am
  attaching a file with this set of messages.
