Public bug reported: After locking the screen and waiting for the displays to go dark, moving the mouse pointer wakes both screens, but only the external monitor shows the blurred desktop background. Moving the pointer to the internal display results in the cursor showing on a dark background until a key is pressed or some time passes. Without the external display attached, sometimes it would wake normally, but sometimes the screen simply stays dark, and all mouse movements or key presses elicit no response. Only switching to TTY and back would allow the screen to revert back to the cursor on black screen until key press situation. Then, after logging in, plugging in the external monitor doesn't wake the monitor. The laptop recognizes it and moves it as the primary display, but the monitor doesn't get the HDMI signal. Relocking and unlocking brings it back.
