Ubuntu Mate 20.04 - switched o Wayland UI and unable to restore initial Mate UI configuration

because of my curiosity, I've decided to check Ubuntu on Wayland UI. That was a huge mistake.

I've lost: 1) Mate login screen, which looks like in gnome and 2) Notifications became un-clickable and look like in gnome. They became blurry when I hover them and I'm clicking through them but can't click them to bring the app related to it to the front.

I've tried removing gdm3, that was also a mistake I was unable to start Mate. I've seen in the boot logs that ubuntu is unable to start lightdm and unable to find my GPU (I'm on Intel/Nvidia - prime). I managed to log-in and install gdm3 back using recovery console.

Can I somehow bring my Mate UI back to the state before I switched to Gnome? The layout can be reset, I don't mind, I can set it again... all I want to have is my Mate UI :)

Any ideas?

My issue has been resolved now.
Obviously I've reinstalled all packages mentioned in the post above as well. However, it did not help. So I've started digging how the config for greeter and notifications should look like.

I've checked what kind of notification services I have by running:

grep -r org.freedesktop.Notifications /usr/share/dbus-1/services/

that gave me:

/usr/share/dbus-1/services/org.freedesktop.Notifications.service:Name=org.freedesktop.Notifications

/usr/share/dbus-1/services/org.freedesktop.mate.Notifications.service:Name=org.freedesktop.Notifications

So I've disabled the first one by running:

sudo mv /usr/share/dbus-1/services/org.freedesktop.Notifications.service /usr/share/dbus-1/services/org.freedesktop.Notifications.service.disable

In addition, I've checked my lightdm config by running:

lightdm --show-config

that gave me:

greeter-session=lightdm-gtk-greeter

user-session=<can't remember now what was there>

I've changed that to:

greeter-session=slick-greeter

user-session=mate

I've restarted my laptop after doing that. Since now both the greeter and notifications work again.
