after turning on my laptop from sleep, there is not text anywhere

[Mohammad Ka]

the screenshot explains what happened very well! I had this problem several times, even after a fresh install, its not happening every time that I wake my laptop up from sleep, but it happens, and it is causing me problems. I've not changed the default installed graphic driver btw.
