The issue seems to remain with kernel 4.18.5 with a small difference that the screen does not turn black anymore, after pressing the Fn-Brightness down key many times. I have added the dmesg output with DRM debugging enabled. Is this sufficient information or is more needed? If the drm-tip usage is a necessity, please provide detailed step-by-step instructions how to do that.</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> </ul> </body> </html>
