[SOLVED] Blank Screen Instead of Login Screen

[Zead]

Worked fine before, I reinstalled Linux Lite, and now I'm sometimes getting blank screen with a mouse cursor instead of login screen, also when I lock screen. The only thing I can do is press power buton to shutdown computer.

I don't dual boot, and I disabled blank screen option, in power / lite locker settings and even in screensaver settings. Someone encountered it?
