  22       <div class="date">31st May 2012</div>
  23       <div class="body"><p>A few days ago my color calibration gadget
  24 <a href="http://www.hughski.com/index.html">ColorHug</a> arrived in the
  25 mail, and I've had a few days to test it.  As all my machines are
  26 running Debian Squeeze, where
  27 <a href="http://packages.qa.debian.org/c/colorhug-client.html">the
  28 calibration software</a> is missing (it is present in Wheezy and Sid),
  29 I ran the calibration using the Fedora based live CD.  This worked
  30 just fine.  So far I have only done the quick calibration.  It was
  31 slow enough for me, so I will leave the more extensive calibration for
  32 another day.</p>
  33
  34 <p>After calibration, I get a
  35 <a href="http://en.wikipedia.org/wiki/ICC_profile">ICC color
  36 profile</a> file that can be passed to programs understanding such
  37 tools.  KDE do not seem to understand it out of the box, so I searched
  38 for command line tools to use to load the color profile into X.
  39 xcalib was the first one I found, and it seem to work fine for single
  40 monitor setups.  But for my video player, a laptop with a flat screen
  41 attached, it was unable to load the color profile for the correct
  42 monitor.  After searching a bit, I
  43 <a href="http://ubuntuforums.org/showthread.php?t=1347896">discovered</a>
  44 that the dispwin tool from the argyll package would do what I wanted,
  45 and a simple</p>
  46
  47 <p><pre>
  48 dispwin -d 1 profile.icc
  49 </pre></p>
  50
  51 <p>later I had the color profile loaded for the correct monitor.  The
  52 result was a bit more pink than I expected.  I guess I picked the
  53 wrong monitor type for the "led" monitor I got, but the result is good
  54 enough for now.</p>
