My Lubuntu 18.04 (as a VirtualBox 6.0.10 virtual machine) is just upgraded to
Linux pbox 5.0.0-23-generic #24~18.04.1-Ubuntu SMP Mon Jul 29 16:12:28 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
with an apt upgrade. After the upgrade, the VM shows a black screen with a cursor in the upper left corner, and seems to hang.
Does anyone have similar experience with the new 5.0 Linux kernel, and know how to fix the problem?
FYI, I can go to the GUI anytime after hitting Ctrl+Alt+F1 and then Ctrl+Alt+F7 without a problem. A systemd-analyze blame didn't show anything taking an excessive amount of time (3 seconds max) during reboot. But if I don't switch manually, the black green never disappears.

By the way, I got the new kernel via apt-get as follows:
sudo apt-get install --install-recommends linux-generic-hwe-18.04
I have got the similar issue. After reboot my VirtualBox machine. It won't boot to GUI but the terminal in "emergency mode". It just can't go into default mode. I have got 5.0.0.25 and 5.0.0.23, both doing the same thing.
I have got the problem solved. It appears that the attached USB devices (bluetooth and external HD) and their relevant settings are stopping the system booting to default mode. After detached them and disabled those settings, all good. Just re-attach and re-apply the settings, everything's up and running.
I, too, received the 5.0.0-23-generic kernel today, after doing my typical
sudo apt-get update
No black screen, however. So far, everything seems to work.
