I setup a new VM to try this bug but sorry 1. I got a graphical dialog asking the disk password 2. systemctl status plymouth-start shows that it exited successfully. I don't get a login windows but looks like X.org crashes with a reference to vboxvideo_drv.so which is a VirtualBox bug it seems. So, if any of you guys can get a coredump with debuginfo it would be the most appreciated. I'll be testing on a laptop as a second resort.
