changed /etc/default/grub and attached. Also attached /var/log/dmesg The external display does not turn on at boot but by requesting different "Display" GUI settings the dock is rebooted (Ethernet connection is stopped and started) and then sometimes the external display is started but usually with incorrect settings such as wrong aspect ratios and mirrored instead of separate. Also, the mouse (not attached to the dock) becomes unresponsive for several seconds at a time. -- John
