And indeed, switching back and forth from these two debug settings, it either works or not. Oh fun... ;) As a side note, the above mentioned 'No connectors reported' message is triggered by my trusty old (default) kernel param i915.panel_ignore_lid=0, so no change actually.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
