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

Tom Fogal, 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 test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release 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>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc5

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.

  10de:08a2 Screen corruption on Macbook Air (Nvidia 320M)

Bug description:
  Binary package hint: xorg

  I just got a Macbook Air and tried to install Ubuntu on it.  Booting
  up the main install disk resulted in some crazy screen corruption, and
  the left inch and a half or so was completely useless, since it did
  not appear to update other than randomly moving bits (described
  below).

  It is hard to describe.  It looked as if I had a normal desktop, but
  overlayed on top of it was a series of 3cm vertical 'bands'.  There
  was a staircasing effect between bands, as a small horizontal line
  connected them but fell between successive bands.  On top of all this,
  pixels seemed to 'move' awkwardly, like they were dancing around after
  too many beers.  If I had to guess, I would say my video card and
  display device disagreed on the resolution, and on top of that
  somebody Snow Crashed my desktop.

  Switching back to the console via ctrl-alt-f1 does not fix the
  problem; my console was messed up in similar ways, though it looks
  more like just plain Snow Crash then.  There was no color in the
  console, of course, so I guess it just must be hard to see any banding
  artifacts, even if they are still there.

  I guess is the wrong place to mention it, but as a side note: the xorg
  folks semi-recently made "DontZap" the default, i.e. disabled ctrl-
  alt-backspace.  Please make it the default on Ubuntu, it's a real pain
  to debug this kind of thing when you can't kill X.

  The fix is simple: remove "quiet splash" from the grub boot lines.
  Everything works then -- with both the nvidia proprietary drivers and
  nouveau.

  It might be important to note that my screen seemed fine until X
  started up, so it seems to be some poor interaction between the splash
  screen (I guess) and X's KMS?

  This is 10.10, maverick.  I didn't try an update after installing from
  the CD, because it was too difficult to see what I was typing.
