[Bug 1122373] Re: 107042 might have come back in new form (unity + nvidia -> unusable system)

[Arlie Stephens]

What I eventually did to recover was something like:

dpkg -l | grep nvidia

followed by

sudo apt-get remove

of everything found above.

I'm not sure now whether this was the headers dependency issue
recurring, or some other nvidia problem. There were some error messages
at one point that sugegsted that something was unhappy because my system
did not claim to be a "dell" - it's a lenovo T430.

At this point my theory for how to keep my system stable is to stay with
the generic graphics, and never tough nvidia drivers again ;-(

Title:
  107042 might have come back in new form (unity + nvidia -> unusable
  system)

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  This morning when I rebooted my 12.10 system it was essentially
  unusable. I suspect it was broken by installing updates, using the GUI
  tool that's part of unity. I believe I have nvidia. I'm pretty sure
  the update tool has been giving me new kernels regularly; I'm guessing
  that while i had a functional nvidia driver in my prior kernel, I
  don't have one in the latest, due to some variant of this bug.

  I'd happily attach logs from before rebooting, except the failure mode
  involved complete inability to get any kind of shell access. I'm now
  booted from DVD, with a request for help on Unbuntu forums which
  contains more detail http://ubuntuforums.org/showthread.php?t=2114956

  I don't have enoguh information to know for sure that I hit a variant
  of 106848/107042, but it smells like I did. I would have had the fix
  mentioned by cjwatson in bug 107042 comment 29, if that really went in
  on or before Jan 3, 2013.

  For what it's worth, I recently installed kernel-headers or some
  variant of it, in an attempt to get a recent version of cprofile to
  build from source.   Perhaps that's a/my source of scrambled
  dependencies.
