[Sanjul <s.sanjul@xxxxxxxxx>]

Tried the upstream kernel v4.0-rc2-vivid. It seems to have no issues with the screen static after returning from a hibernation.
Intrestingly even after removing the v4.0c build, the problem  seems to be fixed when I boot into 3.16.0-31-generic x86_64
What was really happened there? I was under the impression that these kernels were isolated on their own..

[ btw, the wifi isn't working in kernel v4.0-rc2, that's why I removed
it]

Title:
  Static on the screen after returning from hibernation

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After returning from the hibernation ( was hibernated using the
  command sudo pm-hibernate), the screen comes out very ugly. Most of
  the text on the screen is unreadable due to missing pixels. Even for
  the newly typed text ( especially the caharacer 'h'), lot of pixels
  missing everywhere.

  This problem is found everywhere, from newly opened windows to, menus, appswitcher, logout dialogue, everything!
  And only way to get back to normal, so far, is to restart
