The problem still occurs, even with invoke-rc.d. The cause seems to
be that when lightdm is restarted, the old X server it started isn't
killed (well, at least this time). I've attached the 3 log files.
A "ps -aef | grep lightdm" shows:
root 8346 1 0 11:58 tty7 00:00:00 /usr/bin/X :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
lightdm 8374 1 0 11:58 ? 00:00:00 /usr/bin/dbus-launch --autolaunch 067ff1990bad78d604c7357b4b420d9e --binary-syntax --close-stderr
lightdm 8375 1 0 11:58 ? 00:00:00 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
lightdm 8377 1 0 11:58 ? 00:00:00 /usr/lib/at-spi2-core/at-spi-bus-launcher
lightdm 8381 8377 0 11:58 ? 00:00:00 /usr/bin/dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3
lightdm 8384 1 0 11:58 ? 00:00:00 /usr/lib/at-spi2-core/at-spi2-registryd --use-gnome-session
After killing process 8346 (the X server), the lightdm processes
disappeared, and I could restart lightdm.
