Oh, yeah: [drm:intel_dp_start_link_train [i915]] *ERROR* failed to enable link training [drm:intel_dp_complete_link_train [i915]] *ERROR* failed to start channel equalization It was like a was moving monitor here and there. I turned it off, disconnected, closed lid of laptop, connected. Laptop also suspended by closing the lid. So I really don't know what triggered this... It definitely happened 7 seconds before suspend. So we can exclude suspend at least.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
