I've never seen this before, after doing a "sudo shutdown -r now" or a reboot as root, the result is my wife's account comes up. Check the user accts and I'm still the admin. I was playing with Virtual box, wanting to speed in up. When starting MS 10, I received an error about AMD-V disabled in BIOS, hence a restart. Everything I change in VB was put back. I should have not touch anything to day. LOL
I just installed 20.04 yesterday.
