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

 

You have been subscribed to a public bug:

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)
HDMI1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 519mm x 324mm

   1600x1200      60.0  
   1680x1050      60.0  
   1280x1024      75.0     60.0  
   1152x864       75.0  
   1024x768       75.1     60.0  
   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.
