This is happening to me since today after applying the latest updates. I updated 5 days ago so the bug is between the last 5 days and today. It shows like this. After doing the complete update process I reboot it and after the login screen (lightdm) I get a black screen. If I press CTRL+ALT+BCKSPC I can see the icons of the Desktop for a split second, similar to eye blinking and then I am back in the lightdm login screen.
The only way I am writing this is from the guest session. I can't use the account from where I did the upgrade or another account for work. Only the guest session. My hardware is a HP DV6000 Laptop with an Intel video card.
