Can't log back in

I’m running Xfce after using a very buggy deepin 20 beta.

After using Xfce for a while the lockscreen came up and when logging in I was not able to type in the login box! Had to force shut down. How can I correct this problem?

ah :wink: now i do understand… xflock4 on the other post it sounds like login screen (lightdm) was causing this…
You could disable xflock4 in settings or switch to another locker like light-locker:
sudo pacman -S light-locker
then change settings to use it instead:
xfconf-query -c xfce4-session -p /general/LockCommand -s " *light-locker-command --lock* " --create -t string
or with settings editor:
