[Bug 859389] Re: [i915] DVI monitor via adapter to DisplayPort is reported as HDMI.


Daniel van Vugt, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your

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

Status in “linux” package in Ubuntu:

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

  This occurs on Ubuntu 11.04 and 11.10beta2.

  $ grep conn /sys/class/drm/*/status

  $ 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)

     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

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

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