Autologin problem after mintupgrade from 21.3 to 22 (Cinnamon)

[enigma131]

Hi,
I have successfully upgrade via mintupgrade to latest version.
All is working fine except autologin problem, it was working perfect on previous version.
Each time I restart the computer, it ask me for login password, I don't want this because I'm the only user.
GUI setting is OK and same as before, and lightdm.conf is ok too.
Via new Wayland (experimental), autologin is working ..but I need x11.
I have done a forum thread there, but only response is to revert V 21.3 ... :

I think It's a bug from upgrade process.
How to solve this issue ?

ps: I have fisrt post in wrong section

Same issue as well. At first it was a black screen, booted to rescue kernel. All fine there. Feels like there is a stale package, or not all packages were installed/configured properly.

lightdm-autologin-greeter doesn't seem to do squat whether it's installed or removed. The gui doesn't do anything either. Modifying /etc/lightdm/lightdm.conf.d/lightdm-autologin-greeter.conf and /etc/lightdm/lightdm.conf does nothing, even though it's configured to mirror working installs.

I don't know what's going on, but something is preventing it from working and half the time it just black screens.
This was an upgrade from 21.3.

Here is my hardware info for posterity:

I've narrowed down the black screen upgrade issue to fractional scaling. Standard scaling of 100/200/etc has no issue. But when the desktop is set to 125%/150%/etc, it can not load or boot properly. This worked pre-upgrade, and is consistently failing now. Perhaps a stale configuration is present or a package is missing where it can properly identify the screen resolutions for it to scale properly. What I have done in the meantime is to reduce the overall display resolution from 2k to 1920x1200(it's on a legion laptop). This will give me time to do a full backup and wipe the drive with a new install, and hope it isn't a LM revision issue.

I have a look in journalctl:
