In the long run, that's the plan across all panels. I think you can currently try it with i915.fastboot. Might work, might not. However, that will only help the takeover at boot. If the driver does not know how to properly enable the display, it'll fail the next time you do a modeset anyway.</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 QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
