Fatal server error:
no screens found

I have tried with HPD option set to Off, Swap, Normal without any success.

Please find in attachment the xorg.conf, normal Xorg.0.log and Xorg.0.log verbose 7 and the rom file.

I have tried to fix the problem myself without any success i have very limited C/C++ clue. I don't understand why RHDConnectorsInit don't work and return "Card information has invalid connector information".

Thank you very much

Best Regards,

Nicolas DEFFAYET
