I have Xubuntu 20.04. It was originally Ubuntu and then I added xubuntu-desktop. It was also initially 19.04 and I upgraded to 20.04 via 19.10.
I'm using Xfce and when screen locks with password I have to enter unlock password twice. I'm not sure about the origin of those screens but one is using login manager background and second one is using desktop background.
To be worst, sometimes second unlock manager can't get focus to password imput box and I can't enter password and I'm forced to restart lightdm:
sudo /etc/init.d/lightdm restart
Then I can regain contorl over laptop, but I'm loosing session.
My question is: How to get rid of one of unlock screens?
