Linux Mint Cinnamon changes its lock screen to Ubuntu's

[wheattobread]

So I was playing with my computer to change its theme. While doing that, I/Linux Mint changes the normal background into that of Ubuntu 20, I did not know what the problem is. I have an attachment here. If you got your time, please help me out. Thanks.https://drive.google.com/file/d/1IXjyZ2 ... sp=sharing

I'm sorry, but I don't see the problem. You say 'background'. Which background is unexpected? Where in the video does it go bad for you (0 - 51 seconds)? Which theme did you select? I assume you could get back to your old theme and all would be good?

I'm sorry for the confusion but what I mean was the login screen. I use Mojave theme

It look like you installed gdm3 somewhere along the lines. Following the steps here should get you going in the right direction: https://itsfoss.com/switch-gdm-and-ligh ... ntu-14-04/
