Title:
  System Stutter When HDMI/Displayport Monitor Is Connected

Status in “linux” package in Ubuntu:
  In Progress
Status in “linux” source package in Precise:
  Confirmed
Status in “linux” source package in Quantal:
  Confirmed

Bug description:
  With a fresh install of Ubuntu 11.10 x64, the system has many
  "microfreezes" when I connect an external monitor via HDMI. These last
  maybe 10ms and occur about once per second. As I move my cursor around
  the screen, it stops motion during these microfreezes, causing a very
  irritating stutter effect. This only happens when using HDMI- when
  connected via VGA to an external monitor, the system behaves smoothly
  as expected.

  I started a thread about this a long time ago, but I never did find an
  answer: http://ubuntuforums.org/showthread.php?t=1817910
