I have successfully installed Mate Olivia and at first everything was quite normal. But then out of the blue (possibly after updates), the menu button has completely disappeared from the left bottom of the screen. I am limping along with Alt+F1 but I really would like to have my menu button back.
If anybody knows an easy cure, I would appreciate input. I am not a very versed Linux user so please make the answer such that a Linux novice can understand it.
