Description Harald Judt 2011-12-02 15:14:51 UTC
This might not be a bug, but a few kernel revisions ago, DVI-0 became active:

Screen 0: minimum 320 x 200, current 1440 x 900, maximum 8192 x 8192
DVI-0 unknown connection (normal left inverted right x axis y axis)
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  
   512x384       120.0  
   400x300       120.6  
   320x240       120.1  
LVDS connected 1440x900+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1440x900       60.0*+
   1280x854       59.9  
   1280x800       59.8  
   1280x720       59.9

   800x600        59.9  
   848x480        59.7

   640x480        59.4  
VGA-0 disconnected (normal left inverted right x axis y axis)

Hardware: Lenovo Thinkpad T400
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3400 Series

What's this DVI-0? LVDS and VGA-0 (when connected) work fine, and DVI-0 does not hurt, but still I thought I'd report this here in case this shouldn't be as it is now ;-)

It's on a docking station.  As to why it's suddenly getting detected, can you bisect?
