Ubuntu 18.10 (Guest VirtualBox) - black screen after install Guest Additions and reboot
- Ubuntu 18.04 - host
- VirtualBox 5.2.10
- Ubuntu 18.10 - guest
After install Guest Additions and reboot i see flashing boot text and finally black screen.

I had the same issue, my solution was to increase the Display Memory to 128MB.
