I have the same problem as the one described by Michael bellow: the
Intel Graphic card produces eye strain and headache after some minutes
of using it. I found a lot of people complaining on the same problem,
but no solution. I tried lowering the resolution, increasing the PWM
frequency, but without luck. I also installed an old version of intel
drivers (2.20.12), because the subject of this email was "with **new**
Intel drivers", but it didn't help.
I have a new HP Folio 9470m, with the Intel HD 4000 graphic card, and
I cannot use it. Even when connecting an external monitor, I have the
same problem. When I connect my old laptop, with an nvidia card, to
the same monitor, the eyestrain disapear, so it must be the Intel
card, or its driver.
I will be glad to provide any information you consider relevant. I can
do whatever test you want, but please, do not ignore this message. I
am not the only one to have this problem:

I am on (Arch) Linux, but I saw some reports on Windows too.
What is output from 'lspci | grep VGA'?
Exactly what model is your external display?
Does disabling compositing help?
Is it better if you boot a Live Linux media from a year or two or three ago,
e.g. Knoppix 7.0.5 or openSUSE 12.3 or Mageia 2 or Fedora 18?
