[Bug 614238] Re: Intel Core i3 External Monitor Wavy Output

[Kent Lin]

** Description changed:

  A similar problem with Lucid was reported mainly by users of ATi Radeon
  graphics hardware. I also experienced the "wavy" output in Lucid,
  although the graphics h/w is the integrated intel that comes with the
  Core i3 processors.
  
  It is easy to reproduce. Just plug in an external monitor or projector.
  The output is not stable/solid and has waves that make it unusable.
  
  I tried the Maverick Alpha3 to see if it had been addressed in the
  2.6.35 kernel but the problem is still apparent.
  
  The LCD display of the Laptop is rock solid and sharp. This only affects
  the external VGA from what I can tell. I do not have any hdmi devices to
  test with so cannot confirm if the symptoms are just VGA or any external
  monitor connection.
  
  Similar bug reports from Lucid include: 537640, 541501, 557814, 562138
  although these all seem to relate to the ATI chipsets, the description
  of the problem sounds the same.
  
  I am happy to try upstream kernels and build/patch/compile if necessary.
