This gives a good kms on a 3.13 kernel (no black screen anymore, console OK), but X fails with garbled display. So I just add the correct mode to xorg.conf (attached), and it's ok now. I will try later the latest intel-drm tree to see if it has been fixed upstream, but I think it is "just" that the intel CRC do not manage to get the correct EDID to the attached display.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
