[Hernando Torque <855133@xxxxxxxxxxxxxxxxxx>]

** Description changed:

  Starting with Ubuntu's kernel 2.6.39-0.5, xrandr probing takes a couple
  of seconds with only one output connected (internal LCD of ThinkPad
  T510).
  
  This probing also negatively influences lightdm (see bug 828112).
  
  Comment #11 in that bug report suggests to ignore HDMI outputs via
  xorg.conf, which actually restores the behavior of older kernels and
- running 'xrandr' becomes a lot faster.
+ running 'xrandr' becomes a lot faster (in my case it's sufficient to
+ just ignore HDMI1).
