I've installed Ubuntu 18.04, and everything worked excellent until I decided to try Unity desktop. Bottom line – I've uninstalled unity desktop completely.
But! I have some stuff that didn't recover to previous state.
First is the login screen that have changed, and I want to bring back the gnome native login screen.
Second is the Lock screen (that is shown on wake up). Before unity it was the gnome's one, that you can change it's background in the background properties.
After unity
it changed to annoying login form that doesn't work if the keyboard layout is not english, and you just can't switch between layouts in this form and all the window around it. So if before sleep I was using hebrew or russian layout, on wake up I just cant log back in, and I have to restart the pc.
How can I switch back to normal gnome stuff?
Thanks!

Issue the command
At some point, you will be asked which display manager to use. The gdm display manager is the default for gnome. After installing Unity, you have switched to lightdm.
After logging out and logging back into the default Ubuntu session with the gnome desktop, you can remove the unity session by uninstalling "unity-session":
Further cleanup may be obtained by autoremove:
This removes all packages that were automatically installed to satisfy dependencies for "unity-session".
