If I shutdown and unplug the external HDMI monitor, then power on, the internal display only shows the initial UEFI message, the screen appears grey, then it goes dark. If I then plug in the HDMI (not changing the power state) I can get a tty with ctrl-alt-f1, login, and run startx. MATE then appears, but only the non-panel part of the display. Also the monitor arrangement is flipped, but I think that is a minor MATE problem I noticed in 18.04 after a cli startx.
