I've just upgraded my Kali today (I ran apt-get upgrade) and then I've rebooted my computer, but something weird is happenning. First I'cant open my terminal, when I press Ctrl+Alt+T my terminal appears just for few seconds, then everything is closed and my session ends, I'm sent to the login again. I have another problem, I can't see any Icon of any application I can see just their names. How can I fix it? Is something about my video card? I will be grateful if anyone helps me.
