Title:
  [i915] DVI monitor via adapter to DisplayPort is reported as HDMI.

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I have a DisplayPort with a passive DVI adapter plugged into it to run
  my DVI monitor. However the i915 module seems to want to call this
  connection "HDMI1".

  Call it DisplayPort or DVI. Either would be correct. But HDMI is
  wrong.

  This occurs on Ubuntu 11.04 and 11.10beta2.

  $ grep conn /sys/class/drm/*/status
  /sys/class/drm/card0-DP-1/status:disconnected
  /sys/class/drm/card0-HDMI-A-1/status:connected
  /sys/class/drm/card0-VGA-1/status:disconnected

  $ xrandr
  Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 8192 x 8192
  VGA1 disconnected (normal left inverted right x axis y axis)

     800x600        75.0     60.3  
     640x480        75.0     60.0  
     720x400        70.1  
  DP1 disconnected (normal left inverted right x axis y axis)

  This is probably because the DisplayPort is running in DVI/HDMI mode
  [http://en.wikipedia.org/wiki/DisplayPort#Compatibility_with_HDMI.2FDVI]

  But it's still wrong to call a DVI connection through DisplayPort
  "HDMI".

  This bug might be caused by the fix for bug 702125.
