nvidia-graphics-drivers-384 (384.111-0ubuntu0.17.10.1) artful; urgency=medium

  * SECURITY UPDATE:
- CVE-2017-5753 (LP: #1741807).
  * New upstream release:
- Added support for the following GPUs:
  o GeForce MX130
  o GeForce MX110
  o GeForce GTX 1050 Ti with Max-Q Design
  o Quadro P500
- Fixed a regression that prevented displays connected via some
  types of passive adapters (e.g. DMS-59 to VGA or DVI) from
  working correctly. The regression was introduced with driver
  version 384.98.
- Fixed a bug that caused Quadro M2200 GPUs to enter the lowest
  available PowerMizer performance level when under load.
  * debian/templates/control.in:
- Add Replaces/Conflicts/Provide for libcuda-9.0-1.
  Thanks to Graham Inggs for his contribution.

[Bug 1717151] Re: driver installation might not build initramfs then cause dark screen after switching to nvidia

[Łukasz Zemczak]

Hello Alex, or anyone else affected,

Accepted nvidia-graphics-drivers-384 into artful-proposed. The package
will build now and be available at https://launchpad.net/ubuntu/+source
/nvidia-graphics-drivers-384/384.90-0ubuntu3.17.10.2 in a few hours, and
then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-artful to verification-done-artful. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-artful. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!
