zub, 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, and please do not test the daily folder) following
https://wiki.ubuntu.com/Kernel/MainlineBuilds ? It will allow additional
upstream developers to examine the issue.

If the test 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 bug 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, Y, and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, 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
bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  [Acer Aspire 5250] Black screen after upgrade to 3.19.0-22-generic

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After upgrade to linux-image-3.19.0-22-generic on Acer Aspire
  5250/HMA51-BZ there is nothing displayed after Grub. Playing with
  (Ctrl-)Alt-F1, F2, ..., F7, F8... doesn't have any visible effect - so
  neither VT nor X is visible. Removing "quiet splash" from kernel
  arguments also doesn't show anything after the message from grub that
  it's loading the kernel.

  The laptop seems to boot normally, I can hear the lightdm sound that
  it's ready, but I cannot see anything on the display. I can log in
  remotely. The backlight is on, so it's not a cause of no backlight. (I
  checked this by poking around /sys/class/backlight and I see it's set
  at full brightness.)

  If I boot linux-image-3.19.0-21-generic everything works OK.

  I don't see anything obvious when I look at the diff of dmesg between
  3.19.0-21 and 3.19.0.22, but if it's useful I can attach dmesg from
  3.19.0-21.

  According to lspci this is the GPU:
