---------------
nvidia-graphics-drivers-331 (331.38-0ubuntu5) trusty; urgency=medium

  [ Alberto Milone ]
  * debian/dkms_nvidia/patches/register-VT-switch-requirements.patch:
    - Make sure to call pm_vt_switch_{required,unregister}(), so that
      the kernel knows that the driver requires a vt switch at
      suspend/resume time. This resolves a corruption issue on resume
      from S3 (LP: #1210077).
      Thanks to NVIDIA for the patch.

    debian/templates/libcuda1-flavour.shlibs.in,
    debian/templates/nvidia-libopencl1-flavour.shlibs.in:
    - Separate .shlibs for libcuda1 and nvidia-libopencl1
      (LP: #1260974).
