I lock the screen and let the monitor blank. After a few more seconds the monitor will go into it's power saving mode. (If I move the mouse now the monitor will wake up again.) After waiting a few minutes I move my mouse, nothing happens. Then I unplug the HDMI cable and plug it back in, monitor wakes up. The laptop lid is closed the whole time, AC adapter connected.</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>
