    Ubuntu 14.04 wrong monitor port is selected by default

    yurtesen

      I am using ubuntu 14.04 with latest catalyst driver using kaveri apu on an asrock motherboard.

       

      The problem is that once computer boots, if monitor is not turned on, the fglrx driver selects CRT1 as default monitor (although nothing is connected there)

      # xrandr

      Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 16384 x 16384

      DFP1 disconnected (normal left inverted right x axis y axis)

      DFP2 disconnected (normal left inverted right x axis y axis)

      CRT1 connected primary 1600x1200+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

         1600x1200      60.0*+

         1400x1050      60.0

         1600x900       60.0

         1280x1024      60.0

         1440x900       59.9

         1280x960       60.0

         1366x768       59.8

         1360x768       60.0

         1280x800       59.8

         1152x864       60.0

         1280x768       59.9

         1280x720       60.0

         1024x768       60.0

         800x600        60.3

         720x480        60.0

         640x480        59.9

      If monitor is on, it selects the correct port

      # xrandr

      Screen 0: minimum 320 x 200, current 1280 x 768, maximum 16384 x 16384

      DFP1 disconnected (normal left inverted right x axis y axis)

      DFP2 connected primary 1280x768+0+0 (normal left inverted right x axis y axis) 566mm x 339mm

         1280x768       59.9*+

         1280x1024      60.0

         1280x960       60.0

         1280x720       59.9

         1024x768       75.0     70.1     60.0

         800x600        72.2     75.0     60.3     56.2

         640x480        72.8     75.0     66.6     59.9

      CRT1 disconnected (normal left inverted right x axis y axis)

      Now, how can I force the fglrx to useDFP2 by default?

      There are no BIOS options to select the DVI port as default port.

      Thanks!
