Looks like Ubuntu will replace LightDM in their flagship 17,10 GNOME release. Pity. They won't support LightDM much either except for bug fixes.
I find LightDM's GTK greeter to be very configurable whereas GDM is a bear. You have to hack the code to replace the battleship gray wallpaper in the greeter, and as soon as it updates you are back to the old greeter look. :thumbsdown:

Yeah, not completely understanding why they're dropping LightDM.  Sounds like it smoothes the transition to a Gnome DE if they switch to GDM over LightDM.  I thought LightDM was more agnostic to DEs, and customizable.  I've also used LXDM, so I wonder if Lubuntu will fall back to LXDM, or whether they'll continue with LightDM.  Then again, I was happy with SLIM.  I'm not gonna get too worked up over greeter/login manager, as I rarely reboot.  But, bummer...

Additional info
  • Although Linux Mint 18.2 features a newer kernel, this upgrade does not change the kernel on your behalf. This is a decision only you should take.
  • Same goes for the choice of display manager or the software selection. Brasero won’t be removed and MDM won’t be switched for LightDM on your behalf. You can decide to make these changes, but you certainly don’t have to.
  • It is recommended to disable the screensaver before upgrading. If the screensaver activates during the upgrade and you’re unable to log back in, switch to console with CTRL+ALT+F1, log in, and type “killall cinnamon-screensaver” (or “killall mate-screensaver” in MATE). Use CTRL+ALT+F7 or CTRL+ALT+F8 to get back to your session.
How to switch from MDM to LightDM
Warning: This is not recommend for novice users.
First, install LightDM by typing the following commands in a terminal:
  • apt install slick-greeter lightdm lightdm-settings apparmor
When asked to select a default display manager, select LightDM.
Then, remove MDM and reboot by typing the following commands in a terminal:
  • apt remove mdm
  • sudo reboot

Strange that the latest Mint Cinnamon upgrade gives the advice above.

:breakfast:
Install ARCH
You'll never need to install it again

If you install Linux Mint 18.2 off the ISO you get LightDM. However if you upgrade from a previous release MDM stays and that is because of some security concerns with a guest account. I don't fully understand why. The display manager is no big deal since I never even see it with a single user system and autologin.
I'm sticking with Kernel 4.4 as it is an LTS kernel and Mint 18.2 works fine with it. I have upgraded everything else to Mint 18.2 and so far so good.
