[KennoVO <ubuntu@xxxxxxxxx>]

Dear Alberto and others, Could you please please backport this fix to
the 331 driver, which is the most recent one available for 14.04 LTS
(Trusty)? Or at the very least explain why this might not be as trivial
as it sounds? This bug impacts a massive amount of Trusty users, and
failing to get a graphical interface every time the kernel is upgraded
is quite high-profile; a lot of people are abandoning Ubuntu altogether
for it. Our whole workplace may do so soon because one of the programs
we use professionally requires the proprietary Nvidia driver and our
support people cannot afford the time commitment to have everyone use
the non-LTS branches.

I also feel I need to point out that the "users affected" and bug heat
of this report ( lp:1431753 ) are misleadingly low. Most of the users
who trigger this bug land at lp:1268257 . If you look at the stats of
*that* bug and all the recent comments, the whole affair starts to look
like a trainwreck. We tried to make lp:1268257 a duplicate of this bug (
lp:1431753 ), which would presumably bump the latter to the top of the
priority list, but were prevented from doing so by a bug in Launchpad
itself ( lp:1450251 ).

Bug description:
  Filing this against the 340-updates version but possibly the same
  applies to older versions, too. The nvidia source package produces two
  individual dkms packages: nvidia-340-updates, nvidia-340-updates-uvm.
  The problem is that the DKMS build of the nvidia-uvm module runs
  compile steps inside the nvidia modules build directory. This is
  violating the DKMS assumption that each module can be build
  independently (there is no way of describing cross-modules
  dependencies and even more important, the autoinstall step after a new
  kernel is installed will run the modules build in parallel).

  Since nvidia and nvidia-uvm are very dependent on each other the right
  course of action seems to be to combine both sources in one DKMS
  module that produces two kernel modules (this is supported by DKMS).
  For the transition this resulting dkms package needs to have a
  breaks/replaces for the nvidia-uvm package.
