Vanessa Ezekowitz, this bug was reported a while ago and there hasn't
been any activity in it recently. We were wondering if this is still an
issue? If so, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
could you please run the following command from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

If reproducible, could you please provide the information following
https://wiki.ubuntu.com/DebuggingKernelSuspend ?

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) 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. For example:
kernel-fixed-upstream-v3.3.13-rc6

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. As well, please remove the tag:
needs-upstream-testing

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

As well, please remove the tag:
needs-upstream-testing

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:
  Dead screen on resume from suspend Dell Insp. 9200

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Preface:  I was directed to report this as a bug against xorg;
  apologies in advance if it's filed against the wrong package.

  One of my machines is an old Dell Inspiron 9200 laptop.  Contained
  therein is an Intel chipset and ATI Mobility Radeon 9600 graphics
  device.  I am running Ubuntu 12.04 "Precise", from fresh install from
  earlier today.  This machine has the latest Gallium3d drivers
  installed from a PPA ( https://launchpad.net/~oibaf/+archive/graphics-
  drivers/  -- it is a stripped down set of just video drivers and
  necessary related libraries, so I don't have to mess with the full
  xorg-edgers or -swat repositories ).

  Please note that this problem also exists with the default open-source
  Radeon driver supplied with Precise.

  I do NOT use the proprietary driver blob, (it no longer supports this
  machine).

  When I suspend the laptop, it goes down just like it should.  However,
  when I resume it, it wakes up but the screen remains turned off.  That
  is, it appears completely dead to the observer - not even the
  backlight comes on - but I can ssh in from another computer, execute
  commands, reboot, whatever I want as long as it doesn't require me to
  look at the laptop's screen.

  While attempting to come up with a workaround, I ran across the
  vbetool command, namely "vbetool post".  When executed as root (via
  ssh), it resets and wakes up the laptop's video device, but whether
  the laptop is focused on the X display or on a virtual console, the
  screen is garbled.  Whatever is supposed to be there IS in fact there,
  it's just twisted and distorted beyond usability.  The only exception
  is that the mouse pointer is *mostly* intact (slightly distorted).  I
  can move said pointer around like usual, and could possibly even click
  on stuff, log into the display manager, etc., but of course I still
  can't see what I'm doing.

  Switching to another virtual console (e.g. Ctrl-Alt-F1 or 'sudo chvt
  1') and back to the X display has no effect - if it was dead, it's
  still dead.  If it was garbled from having tried 'vbetool post', it
  remains garbled (but the contents change).

  Further, if I disable Kernel Mode Setting with the "nomodeset" boot
  parameter, I am then able to suspend and resume to my heart's
  content.....  Except then the video driver gets downshifted to the old
  VESA one, as Gallium requires KMS.  If KMS is disabled, I can also use
  the old Radeon driver, but then I lose 3D/OpenGL acceleration, so at
  that point I may as well have been using VESA.

  I also tested, briefly, this machine's ability to run Intrepid Ibex
  using the proprietary ATI blob (v9.3) - suspend, resume, 3D
  acceleration all worked as expected in that configuration, but of
  course that version of Ubuntu is quite out of date and unsupported, so
  it got overwritten with Precise.

  I am currently operating on that fresh re-install.  Every partition on
  the machine was re-formatted prior to the install, leaving nothing
  behind from any previous OS.

  Only a minimal amount of additional software has been installed since
  that time.  None of the system's configuration files have been altered
  except for the grub config (when I attempted unsuccessfully to disable
  KMS).

  What I expected to happen, of course, is that the laptop should turn
  on and re-initialize the screen when it comes up from suspend without
  me having to run stuff like vbetool, which doesn't work for me anyway.
