whilst in the black screen state I switched to a TTY and ran ubuntu-bug nvidia-390 - I used the keep option to create the .apport file.
After purging and booting back with nouveau I ran "apport-bug apport .nvidia-driver-390.4lwinjii.apport" to report this issue. If there is a better way to get more logs please let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1764005 Title: Black-screen on boot with nvidia 390 for GTX 960M To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1764005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
