There's no solution :( .I think your case is same as them  :wallbash:

From your vgadump file I got - with radeon bios dump :

And I have collected your frame buffer :

 

               LVDS :    02 00 00 00 40 00 00 00 09 01 00 00 12 04 00 07

                 VGA:     10 00 00 00 10 00 00 00 00 01 00 00 00 10 01 06

               HDMI:     00 08 00 00 04 02 00 00 00 01 00 00 20 01 02 02

DISPLAYPORT:  00 04 00 00 04 03 00 00 00 01 00 00 10 00 03 05

 

You can save this data for future reference & try to correct frame buffer with the help of a specialist :P  , but this time as far I know have nothing to do  :(

Thank you
