Re: virtualbox on ubuntu 20.04 blank screen problem.
Topic moved to "Linux Guests" since your question concerns a guest, not your host OS.
I hear that Ubuntu black screens can indicate that it's running out of disk space, but I'm not an Ubuntu expert.
I do see a couple of other problems, but nothing I would expect to cause a black screen.
The second item indicates that you have someone else's Guest Additions installed, specifically you have the GAs from the Ubuntu fork of VirtualBox. We have no idea what the Ubuntu devs might have done, so their forks are not officially supported. Unofficially it probably works, but 6.1.6 is old.
Another thing to note in that line is that the GAs were loaded at 13 seconds into the boot, which doesn't indicate to me that the guest had any problem.
All told, I'm not seeing a VM problem here. More likely a config problem inside the guest OS.

The first item is that graphics RAM looks a bit low. Your host has plenty of RAM so I would increase this to 128MB.00:00:03.300008 VRamSize <integer> = 0x0000000003800000 (58 720 256, 56 MB)
