I have a partitioned disk on Osx and I installed Elementary on it. It worked till few minutes ago when I installed latest system updates from the store. Now when I try to start Elementary it seems freezed with a black screen and a dash that flashes on the top side of my screen but nothing happens and I'm not able to login in Elementary anymore. How can I solve? What is the problem? Mac it's a MacBook Pro Early 2013
Solved: It was a problem of misconfigured drivers after updates. When it is in black screen => Type fn + cmd + f1 to get into tty1 terminal then login in one of your user already installed on your system (asked automatically by elementary when you log in tty1). After this you can type: sudo apt update apt install --reinstall bumblebee-nvidia bumblebee primus apt install --fix-broken sudo adduser $USER bumblebee //when you're root adduser $USER bumblebee //when you're with no root account (you can exit from root privileges by typing exit) reboot After this you should have been fixed your screen but problem is not completely solved because if you try to update drivers from appcenter , you will face with the problem again. To avoid this you can install definively drivers of a version preventing other updates that might break drivers again. So by command: sudo apt-get purge nvidia* sudo add-apt-repository ppa:graphics-drivers sudo apt-get update sudo apt-get install nvidia-drivers-410 sudo apt-mark hold nvidia-drivers-410 reboot p.s this should work also on windows if you have the same problem
