I have no information on what that mode entails, but it's plausible a fake display is part of it. This seems like the most plausible explanation to me at this point. I don't know if this can be configured in the BIOS, or perhaps jumpers on the motherboard, or something else. But if I'm right, it doesn't look like an i915 driver issue to me. We can keep the bug open for tracking purposes for now, but I think this will be RESOLVED NOTOURBUG.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
