My 5 year old daughter has seriously messed up my log in screen somehow. She can't or won't tell me what she did so I really don't know happened.
The screen is now divided vertically, the left half is normal but the right side is black and has a few sets of dots in a triangle pattern that move around when I move the mouse. The black side of the screen also moves when I move the the mouse to reveal a partial grey background.
As a result I can't get to the shutdown options on the bottom right or select which window manager I want to use. Plus the whole thing looks ridiculous.
Has anyone got any ideas confused is going on ?
I tried setting the log in to automatically log in to an account at startup and then set it back to enable me to choose a user, but the problem is still there.
Everything is fine once I log in but seeing this screwed up log in screen is getting very annoying.
