When i go idle, the screensaver appears, then when type or move my mouse, it dissapears. The problem is that, i can't enter the password, because when i click on the text box, it doesn't do anything, and even if i type my password on the keyboard after clicking the textbox, it still doesn't do anything. The only fix is by clicking the button "Switch User" and that makes me go to the login screen that appears when i boot up my machine, i type the password and it works.
