LightDM fails to start on Upstart based systems

[rec9140]

systems purged of systemd via

apt-get install upstart-sysv sysvinit-utils -y

update-initramfs -u

reboot

System now uses Upstart to boot.

sudo apt-get install lightdm

brings in about 30+ and 247MB worth of packages, but OK...

installs, asks to reconfigure, select lightDM over sddm

reboot

Comes to a CLI console during boot

if you login to the console an error from logind (????? this is an UPSTART SYSTEM!) about can't find file can't start service unknown

If you check /etc/X11/default-manager it has the line

/usr/sbin/lightdm

if you do

sudo service lightdm start

lightdm comes up

enter credentials

when you hit enter after password

"Could not load session"

Can't install KDM to replace it due to dependencies no longer met and package not in 16.0.4.1, used last package available from launchpad.

Can't run XDMCP as sddm does not provide proper X manager login services.

Kubuntu 16.04.1 fully updated

Expect to have a login manager to start local or remote (XDMC) X sessions.

Can you attach /var/log/lightdm/lightdm.log after this occurs?

It should work fine with upstart...

[rec9140 (rec9140)]

I've included the below...

Seems now that startx won't start up...so I may have to rebuild this to start over on this..which won't be till TUE 10/18

dmesg below:

OK... I have time to restest this... and starting from scratch.

Install 16.04, updated to all patches....and updates via

sudo apt-get update
sudo apt-get upgrade

Now to install LightDM over SDDM to get XDMCP capable DM..

sudo apt-get install lightdm lightdm-kde-greeter

HUGE list of dependencies is brought in for this... accept... and go on...

reconfigures to use lightdm as default DM..during the apt process.

reboot to complete.

Get a huge purple screen with little dots all over it... a bar at the top with host name, Network Manager options, restart/reboot options, and a user login screen left side towards the bottom.

Enter password

Can't start session

Can't login to the box at all via ligthdm... to start an X session...

[rec9140 (rec9140)]

Further testing....

Taking a BLANK 16.04 ISO, install...and update...fully updated..

sudo apt-get install lightdm lightdm-kde-greeter

Let that configure... and select lightdm

reboot... IT WORKS!

LightDM Is installed, and brings up an X session!

Create lightdm.conf and enable XDMCP.. IT WORKS!

So, rinse repeat... clean slate.... Do it the way I've done it in the past.. via Synaptic.

This is where I think the problem is!

Synaptic wants to bring in a long list of depends...

Creating a script to get a list from synaptic...this is what it wants to install, below... what happens via apt-get install lightdm lighdm-kde-greeter is far less!

My first test above that failed is via synaptic install of lightdm/ldm-kde-greeter. this is STILL UNDER systemd at this point! I will test moving to BACK TO UPSTART, (thanks, but systemd is not for me, and this is not the space for that debate either) with the working setup shortly....

synaptic installs for selecting lightdm and lightdm-kde-greeter:
