After the last update there was a problem with black screen right after any changes in settings. As soon as I click Apply after absolutely any change or even just no change I have a black screen, but everything works as it was (for example, music plays, etc., the computer works fine, just a black monitor that says “Login not supported.”). I can't remove the task, I can't minimize or expand it, I just have to restart the computer. Maybe someone has encountered this problem? Playing is not possible just.
