Perhaps there is a bug with dash to dock or debian defalut dash. When I enabled dash-to-dock extension and used it for a while, I locked the screen and hang out a little, when I returned I found the dock bar showed on the lock screen. I loggin my account and found it still there even after I disable the dash-to-dock extension.
You can see in the pictures I uploaded, I have disabled the dash-to-dock extension.
I cannot stand this problem any more. I search for the solution, however, there seems to be no solutions for debian. All the solutions I found are for ubuntu to disbale ubuntu-dock with gnome-extensions disable ubuntu-dock@ubuntu.com, but there is no dock configure on debain. How am I suppose to do? Any suggestions will be appreciated.
