Title:
  Very poor performance with xserver-xorg-video-nouveau live bionic
  beta-1 session

Status in xserver-xorg-video-nouveau package in Ubuntu:
  New

Bug description:
  QA suspend test:
  * Needed 10 minutes to get to unlock prompt.
  * After unlocking, 2 minutes passed before desktop was visible.

  I use the nouveau driver under 16.04 on the same machine and suspend-
  return performance can be measured in seconds.  Of course, that is a
  native build, not a live session.

  Hardware:
     - Assembled 2009-04-15
     - Zotac IONITX-F-E Mini-ITX motherboard
        * CPU Intel Atom 330 (1.6GHz, dual-core)
        * NVIDIA GeForce 9400
     - RAM: 4GB DDR3
     - Graphics support auto-selected:
        * Kernel module - nvidiafb
        * Xorg video driver - nvidia-340
     - Permanent storage: SSD 60GB
     - RJ45 Ethernet: Nvidia forcedeth kernel module
     - Mini-ITX enclosure: Habey EMC-800S Silver
