Connecting the dock with drm-tip kernel results in strange picture on external displays (blown up section of screen, displayed in a limited square on one of the external screens). Disconnecting the dock leaves everything blank. Talking laptop to sleep restores laptop panel. dmesg (without debug) is attached. Any help on what's wrong it appreciated (perhaps I built drm-tip wrong). On 4.15.0.30: unable to reproduce with log_buf_size option set to anything. Will try some more. I was able to reproduce it again without kernel options on the 4.15.0.30 kernel. While the screen is frozen, "xrandr -display :0.0 -q" from external ssh actually hangs until I disconnect the dock. xrandr output with screens connected and disconnected during normal operation is attached.</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>
