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

[Arlie Stephens]

Public bug reported:

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.
