Black screen (Solved)

Morning, everybody.
I haven't used Mageia in years and now I'm surprised by how polished and nice to use, I already have it as my main but I've noticed that at times when the screen is suspended, when you return and set the password, the screen is black, I have to press: "Ctrl+Alt+Supr" to display the logout and restart.
What can it be?
I use a Compaq laptop with Intel 4Gb RAM and Mageia 7.1 updated.
