Title:
  [8xxx] Unity/compiz has sluggish performance on dual-head with nvidia
  driver

Status in compiz package in Ubuntu:
  Confirmed
Status in nvidia-graphics-drivers package in Ubuntu:
  Confirmed

Bug description:
  When Unity/Compiz is running with the -nvidia driver and two monitors
  are connected, compiz and/or Xorg will consume CPU time  (50-90% typ.)
  with window activity (opening large numbers of windows, resizing,
  moving, etc.)

  Disabling "Sync to VBlank" appears not to help.

  Duplicate bug #737454 suggests it may be an issue specific to the
  NVIDIA 8xxx series cards with large resolution sizes.

  [Workarounds]
  The issue can be reliably worked around by either disabling one of the displays, or disabling the Unity Plugin in CompizConfig Settings Manager

  The nouveau driver on the same hardware typically does not have the
  performance issue (but may have other issues such as stability,
  rendering it not a valid workaround).

  Some have reported that upgrading to -nvidia 290.03 solves the
  problem; others report it has no effect.  See
  http://www.nvnews.net/vbulletin/showthread.php?p=2493300

  Some have reported that lowering the external monitor resolution to
  match the laptop LVDS resolution brings performance to acceptable
  levels.
