Ihor Romanyshyn, could you please test the latest upstream kernel available 
from the very top line at the top of the page (the release names are irrelevant 
for testing in your release) following 
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional 
upstream developers to examine the issue. Once you've tested the upstream 
kernel, please comment on which kernel version specifically you tested. If this 
bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly 
shown as:
kernel-fixed-upstream-3.18-rc3

This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  [HP Pavilion g6-1322sr Notebook PC] Ubuntu sometimes starts with
  display disabled

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu sometimes starting with display disabled on my HP g6-1322sr. It
  can be 3 times in row, or 10 times all will be ok. Sometimes after
  Ubuntu start, you can hear login screen sound, but display doesn't
  work. To make display work I switch to tty1 (display doesn't work too)
  and make ctrl+alt+del. Help!
