Public bug reported:
I upgraded this Kubuntu laptop using the command "do-release-upgrade -d"
from 12.04 to 14.04. After the reboot, the splash screen did not
disappear and lightdm didn't start. Running the command "start lightdm"
(as root), I got the error message "start: Job failed to start", which
wasn't really helpful. I also tried the command "/etc/init.d/lightdm
start" and now there was some more information:

[ OK ]
Even though there was the "[ OK ]" displayed in the last line, lightdm
didn't start. Due to the message "Failed to find session configuration
lightdm-gtk-greeter" I supposed that the package lightdm-gtk-greeter was
missing. And indeed after I installed that package (+ dependencies),
lightdm started.
As this is a test-upgrade I could return to the original 12.04 system.
On that partition was a file /etc/lightdm/lightdm.conf from 2012 with
this contents:
[SeatDefaults]
greeter-session=lightdm-gtk-greeter
user-session=Lubuntu
Obviously this was a leftover of a previous test with the lubuntu-
desktop. While I had uninstalled lightdm and most of the other Lubuntu
packages, this configuration file was not removed for some reason. And
during the upgrade I was not asked if the config file should be replaced
but the file stayed untouched.
