Hi, thanks for helping, but my problem is worse. Usually, I don't even can open a tty terminal. It freezes completely. Sometimes I can open a terminal by this way when I press F12 before Ubuntu tries to start lightdm. Anyway, I just tried it that you just told me (sudo lightdm restart), but only a cursor appears and disappears after 2 seconds. For a while, I'm using xinit to open a graphical session.
