Actually, I have some more information. This is with a multimonitor setup: laptop and external VGA. The external monitor was set to on and the laptop display turned to off. I now think this may be an issue triggered, at least, by gnome-power-manager. Screensaver is set to blank, but the timeout for powering off the display is shorter. When I lock the screen and is powers off, this issue does not occur. When the screen is powered off by the inactivity timeout, the laptop screen is reactivated upon the subsequent power on and the gnome-panels appear there. This is annoying and disruptive, especially for a still-supported LTS release.

My workaround is to bring up a terminal by pressing Ctrl-Alt-T, and invoking my dirty fix:

$ cat /usr/local/bin/mmfix
#! /bin/sh
set -e
set -u
set -x
